    I’ve used this effect at colleges, comedy clubs and at corporate events for large and small audiences and it ALWAYS kills!!!! A great effect and top notch quality.

    I love the rubik’s cube and I solve it relatively quickly. For me the best product created by promystic. You can see my interpretation on Portuguese television –

    I can’t believe I am the first to review this great little product! I bought the MD Mini more than a year ago and have used it in lots of situations such as planned performance for larger groups, close up or for friends and family. It is perfect for impromptu because it hangs from my keychain all the time. I always have it with me ready to go as the receiver is small enough to keep in my bag. It just requires getting the receiver into a suitable position to be reliably detected – I don’t always have pockets like the fellas so discretely tucked under a bra strap does the job just fine! Even though my friends have seen it in action several times, it stands up to examination and is known as my lucky colour cube and fortune telling charm. It gets requested a lot. The colours provide a great angle to add a ‘reading’ for the participant. This can really pack a punch. It has bamboozled colleagues and waiters in Dublin and American tourists in London – the mayhem is worldwide!

    The battery life is not quite as long as I had hoped. I tried to use the option for switching the Mini on and off with out removing the batteries but it seemed to switch on again. I think this is due to the way it hangs down (which is slightly different to the version shown in the video) and it can sometimes trigger the auto on. But it’s not a huge issue and I seem to get several months from the Mini for sure and turn the receiver off when not in use. If I am worried about it I just change the batteries before an anticipated performance, as they are standard, inexpensive and easy to source. That’s the only reason for 4 stars and not 5. I’d give 4.5 if I could.

    The two things I love about this company are the that the receiver is used for many of the products, making it cost effective and only requiring me to own and carry one. The other is the support they give. I think Craig’s level of customer service is well known but I was very impressed when I bought another item from him recently. He spent a lot of time on the phone with me talking through the options. Rather than just having his eye on the sale he accurately identified what would suit my style and environment and travel needs and it was the less expensive option.. He was spot on.

    But back to the MD Mini… I now have a few products from Pro Mystic and this is the one I use the most. I love it!

    Innocent looking yet lethal when performed, MD is the best combination for any mentalist looking to let a perfectly built prop take care of the technical aspects allowing him/her to concentrate entirely in performance. I have been using Promystic props (almost all of them) for years without any failure, as we know reliability is a plus in our industry and with Promystic and Craig’s top notch customer service we have it!. Many thanks Craig, Can’t wait to see you newest creation, Private EYE.

    This little baby has been my absolute favorite buy from Promystic since I received it. I carry it everywhere I go and it’s always ready to go at a moments notice. If you want a jaw-dropping effect using a ‘normal’ looking prop that everyone recognizes, then this IS perfect for you! It’s been a workhorse in my arsenal and an absolute dream worker! Thank you so much Craig for being the creative genius you are!

    It’s always with me in my Keychain.The best impromptu device ever invented.So innocent and so’s the essence of the promystic products

  7. Rated 5 out of 5


    I have had my mini md for almost 2 years and after literally thousands of performances this thing is one of if not the best purchase I have ever made. It is just small enough where spectators do not suspect anything is inside. It is extremely durable and very reliable. My md gets used at all of my trade shows which are usually 7 hours long and consist of many, many performances and it works flawlessly. I never worry about it not performing as advertised. So many products these days are so misleading with false ads and flashy demos that I very rarely purchase anything but with Craig here I always know exactly what I am getting, a product that delivers what it says it will do. On top of his amazing products Craig has amazing customer service and did not hesitate to talk to me over the phone and help me with a product. Overall top notch product, top not service that you will not get anywhere else!

    With the help of MD Mini, it can achieve much, much more than guessing what color spectator is holding the cube on top. It is a professional tool for mentalist to put in their show to create miracles.

    My highest recommendation.

  9. Rated 5 out of 5


    I have owned this product for 8 months now and I have to say this is a gem. The effect is really strong, the method is undetectable, and the prop looks completely innocent. I carry it with me at all times knowing that I have a reliable and very strong magic routine (keyword being ‘routine’) that I can use to entertain and amaze audiences of all sizes. I use the MD mini in professional walk-around situations all the time and it doesn’t fail to impress.

    In addition to top-notch quality, ProMystic’s service is second to none. I had a problem with the first receiver I got and Craig promptly answered my questions, diagnosed the problem, and sent me a replacement at no additional cost. I haven’t had any problems since then. I’m giving ProMystic my highest possible recommendation.

    I Bought this reputation maker in Blackpool after seeing a live demonstration. It’s been on me since. I literally don’t leave home without it. the best thing about the Mini MD is that it really looks like a part of your keys. I usually just let it rest right there on the table, and when asked to demonstrate something, pick it up and say “let’s try this”. It just looks so innocent!
    By far, my favorite ProMystic product!

  13. Rated 5 out of 5


    MD Mini was my first ProMystic product. The small size and ‘common’ nature of the cube is so disarming to spectators. I travel quite a bit and work at conference venues– that gives me some justification to explain that the cube was a bit of vendor booth swag. It’s hard to explain how innocent the MD Mini looks and feels.

    The construction and reliability is outstanding. In the 2+ years that I’ve owned my MD Mini, it has never let me down.

    I have had my MD Mini for about 18 months. It is such an amazing item — cool and so innocent that I have used it for variations of guessing color selections to a routine akin to Color Match. It is one of my two favorite performance items (the other being Multi Dimensional). So happy that I discovered ProMystic and it’s product line. Craig provides fantastic service.

    What I like about the MD Mini is how innocent it looks. So great for “impromptu” effects!

  16. Rated 5 out of 5


    As an early adopter of Multi-Dimensional, I was thrilled when this pocket-size version came out.

    It’s an innocent looking tool with a remarkable range of uses: 1) straight mind-reading, 2) lie detector presentation, 3) personalized “colors reflect your emotions” presentation, 4) Kurotsuke-style presentation (line up small items on a table for spectators to take one at a time and conceal; you get a signal when someone picks up the little cube), 5) and even for cueing with a secret assistant using the cube (have her send you any number 1-6; or have a standard Rubik’s Cube on the table, and with your back turned your helper cues you which color is on top).

    Although I’ve never done it, you could also place the Mini MD inside a larger item (a photo cube, for example), opening up even more possibilities.

    One big plus is that this Rubik’s Cube keychain looks like a little novelty item you might have picked up in a toy shop or 99-cent store. It attracts no attention or suspicion.

    On the other hand, the MD Mini is pretty much bulletproof, thanks to the sturdy materials and Craig’s quality standards.

    I did have to “unlearn” the color sequence I’d grown accustomed to with my Multi-Dimensional color cube, but that took about five minutes and I was good to go. I haven’t stopped using it since!

    So my first experience with pro mystic got off to the best possible start when i was personally contacted about the md mini which i had been asking about for some time, but had been out of stock. They finally got one and it was offered to me. I obviously immediately purchased and despite being in the uk, it arrived very quickly. So about the item itself; The md mini is absolutely brilliant. Firstly; it looks so innocuous that no one will ever suspect it. The instructions were easy to follow and i was practising within literally a few minutes it works perfectly and battery life is superb. Overall, i couldn’t be happier. Thanks

    MD Mini is a jewel. It looks very innocent but is a killer effect. You can really blow your audiences away by performing MD Mini. The prop is streamlined and the quality ist top-notch, as all the Pro Mystic products are. If you want to perform a routine with a die, then MD Mini is definitely the one you should use!

    The MD Mini is the “perfect effect” for the serious amateur mentalist or the seasoned pro. It packs small, plays big, and provides an opportunity for the performer to do just that — perform. The MD looks “organic” on a keychain, and is always at-the-ready! Batteries are long lasting, as well!

  21. Rated 5 out of 5


    I own the regular MD and the Mini MD but the Mini MD is my favourite – it is always on my keychain and ready to perform at a moment’s notice. Very accurate and reliable and wonderful experience for the spectators. I would recommend purchasing extra colour stickers for the sides as they do tend to come loose and fall off eventually – especially with the Mini MD being in my pocket all day. By far the best ProMystic product for everyday use.

    Hi guys,

    I’ve been looking for a mentalism prop that won’t be cards, coins, business cards or ropes. Recently the show TNT reviewed this little boy and it catch up my attention. How a so small and normal looking object could turn you into a real mind reader. (From the spectator’s point of view)

    I immediately contacted Craig on a Sunday and his answer was sent within the hour ! I’m like that too, to be very fast in my answer but Craig just took some time off his Sunday to take care of me. The mini MD was ready to go, he sent it on the Monday and I received it Wenesday ! 2 days from America to France.. Even french postal service is slower ! (Well, they are slower than everything but it’s another question). I’m a very impatient guy, I sent them a lot of questions during those 2 days, again, they took the time needed to answer me. Couldn’t be happier with the service they provided.

    Then let’s speak of the product in itself. I already have a routine in minds and it fits perfectly ! I started the day after performing it.. Wow. It’s the only word that can describe the powerfullness (is it a word ?) of the effect. It looks like REAL magic. It’s even too powerfull I think.. It all depends on how you will introduce this little rubiks cube. Let’s digress a little bit, if you carry something in a trash bag, people won’t want to touch it or even examine it. A contrario, if you carry it in a velvet bag and that the spectator see you are carring about it, they will immediately care about it too. I don’t say you had to carry your mini MD in a garbage bag ! But Craig and his team has found the perfect motivation of having it on a keyring.

    So small, so innocent but so devious and powerfull. Don’t limit yourself of revealing the colors, use your imagination to come up with others routines and presentations. Stage, parlour, close up.. The places you can use it are endless. Also I thought the receiver was the size of a TV remote.. I was so wrong ! It’s so small you can even finger palm it.

    Ok, now come the bad things.. Well, for some, I must say, I don’t find them to be cons but some people could. First, this is electronic. It means you depend of it, if it doesn’t work, your routine is over. I agree that I’ve been using it only a few times but it works perfect ! The price is a step too.. But come on, look at the effect, I don’t mind paying for a powerful effect, a first class quality prop and a wonderful customer service. Keep in mind you only pay the receiver once then you won’t have to pay for it again if you want others effects from Promystic (which I’m sure you will). Another con is the packaging, the Promystic website is very classy, very elegant but the packaging in which I received my Mini MD doesn’t reflect the elegantness (is this a word also ?) of the website and of the Promystic products. I know you don’t pay for the package but I wish it was a little bit more elaborate. (Yes, I know I’m a little bit “pointilleux” as we say in France).

    I don’t buy a lot of effects and tricks these days but I know my next buy will be from Promystic. I prefer to have one effect per year that will fit a whole act and that is close to real magic than ten single trick DVD.

    Hope my english was easy to understand and that my review was helpful. If you still hesitate on wether you should buy this gem or not, just contact Craig and he will convince you 😉

    I will post here my thoughts on this in a few monthes, after having used it more so I will give more thoughts about it.

    Thanks Promystic, thanks Craig. I’m looking forward to your futur products !

    Mini MD (and receiver)

    I want to review the purchase as well as the item:

    Delivery: super fast and NO DUTY so I was very pleased. 3 days from order to receipt! How on earth did Craig do that? I was so pleased that I didn’t have to pay any extra to get it.

    Service is amazing from Craig and he is really nice guy. As a side note I bought another ProMystic item second hand and the seller had lost the instructions. Craig sorted me out! And I was looking at buying a Para Pad – no question too daft and he was very through about helping me choose! He is a brilliant customer service guy….although that doesn’t really say how helpful and nice he is!

    Simple but effective, no more than needed but not too little either. The Mini MD was perfectly protected and arrived in mint condition.

    Very well written and easy to follow. Tells you all you need to know! The Mini MD also came with a PDF of effects to perform with the Mini MD. Some really great ideas! Although for now I’m sticking with the colour side up idea.

    The Mini MD (Main item):
    The craft work on the cube is amazing. It is impossible to see the join (without the instructions you would not know it opened let alone how to open it)

    The “science bit” (as Jennifer Anniston used to say on the shampoo advert) or the electronics if you would rather:

    Well I can’t comment on the quality of the actual electronics other than to say….it works, it’s easy to use and it’s really accurate with a good range! The coding (to tell which side is up ) is simple and easy to remember.

    Battery life: seems great, used it for a good few hours on the same battery so no problems there.

    I have no idea how it works but it does. It’s so discrete and I love that I can take it anywhere in my pocket or in place ready to go at the flick of a switch.

    I found the battery ran out quite quickly but I think I left it turned on by mistake. My friend takes his batteries out of the receiver when not in use and I have started to do so too. No hassle and it guarantees I can’t leave it turned on by mistake.

    The effect is strong and the method is undetectable and easy! The only problem I have had was a “stage management issue”. I failed to get the colour wrong once out of hundreds of times. It was as the spectator had chosen the white side but she said it was not white. It was “pink” – there is no pink but she was sat under a red stage light! My fault not that of the Mini MD.

    This is a great effect with many many ways to play it, I love that it’s on my key ring and I can use it anywhere, large or small. It’s so much fun and it leaves people blow away! I have to be honest I turn it on and do the effect on myself because it’s so much fun (I know that is very sad …..but it’s true!).

    As it’s modular so I could add Finders Keepers to the set too (which is also brilliant by the way).

    If you can …… Get one! I’m sure you won’t regret it!

    MD Mini is the Promystic product that I use the most. The reason is simple. I can have it with me all the time, and even unlock it while having a casual conversation. I carry my keyring clipped to a belt loop on my pants, so along with my keys the Mini just hangs on my side.

    Often, someone will notice it and comment on it, so that creates the opportunity to put it into play.

    I have both receiver models, but usually carry the key fob receiver when carrying MD Mini.

    The only negative comment I have is that if I carry this in my pocket the color stickers tend to get beat up and shift around. Installing new stickers is quite easy, so this isn’t that big a deal.

    I also purchased the Max Krause Rubik’s Cube that the MD Mini works perfectly with. I use this prop when performing stand up. The colors on the Mini and the full size cube match up perfectly.

    Truly an amazing device. I highly recommend it!
