I really like this. This has (Surprisingly) gotten GREAT reactions. I'm not saying people will remember this forever, but for the gig tonight, people absolutely loved it IN THE MOMENT. It worked perfectly and got satisfactory results/reactions EVERY time no fail.

Only issue is the off button doesn't work the best without a pointy object(you can use finger, but at very specific angle it Seeeeems. Tis good that it doesn't turn off mid performance though) and I wish the charge lasted longer (6 hours is pretty good though... This is me being picky, Charge it in the car and you are goldennn).

Over all, amazing solid, prop-less looking mentalism. Seriously, if you want to look like a human lie detector, or the best deductionist, this is a GREAT start.

This is honestly one of the coolest devices I ever bought.
It’s so small you can hide it anywhere! I was able to use this right out of the box, and being able to tell if the coin is heads or tails just blows people away. I highly recommend this.

I own Sence 2.5, and all I can say is that this new version is excellent, ultra sensitive, programable. There is a big difference in terms of sizes. I just love it, highly recommended.

This device is a must! Accurate as hell, many different methods that can be done any easy to conceal. The only reason I give it 4 stars is there is no app for android users and that made me sad :(. Other than that I've used it and blew peoples minds.

As a rule, I try not to review anything until I've tested it with various audiences a fair amount of time to gauge reactions. As magicians we have our own ideas about how good we think a trick is and if we don't test it we can provide pretty biased reviews. A device like this has many, many possible uses, though the basic "Which hand?" plot is its primary purpose. The price point may seem steep for an apparently simple effect, but trust me when I say, this has gotten me some of THE MOST incredible reactions ever.

You can really mess with people if you use this properly. I know some people worry about looking totally clean, but even when I need to finger palm the device, it totally kills. Never been caught, some people have guessed what's going on, but only in the midst of 12 other guesses and they had no idea which was actually correct. If you do this like 10 times for someone and get it wrong once or twice on purpose it really makes people believe you can get in their heads and understand their psychology. I always start off with, "Are you right or left handed?" then proceed to make some remark about why it would be obvious that they chose their dominant hand (or not depending on what they choose), and I get make up new tells each time they do it. It's super fun for the participant and the audience. I've had a couple of people try to trick me by putting in their pocket, and you can catch them cheating, which just destroys them. I actually hope they try to cheat every time I do it now.

Well made device, super easy to use, and so much fun to perform. Easily one of the best addition to my repertoire in 15+ years.

I have 2 - one that runs on a battery and one that plugs in.
I have used the battery device for several years and am not that confident yet with the plug in; the button has been an issue. Reading some of the comments I am going to use the plug in carefully (and have the battery op in my pocket for an emergency backup). I love the device because it is so close up and personal and I am always make it 100% fun for the participant. Thanks

It’s ok not 100% reliable. What I mean is your movement will most of the time make it inaccurate causing the read incorrect. Even after changing the app settings it’s still off. When it does work somewhat accurate it’s great. A little pricey for something that is not 100%.

It is even smaller than I thought, and with the extra features the free app provides, there are dozens of effects waiting to be done! Very impressive design and reliability.

This is my first device like this and it works perfectly. I did a show with the device and killed with it. It’s simple to use and is limited by your own imagination. Just be careful if you use a smart watch because it will set off the device if you have it in the same hand. I just keep the device in my other hand and it works flawlessly. It’s a steep price, but worth it.

This gimmick is a killer. I have incorporated a magnetic quarter into "Pocket Money" and make finding the coin and divining whether it is heads up or tails up into a finale for a stand-up coin routine. Works like a charm. The small size does not provide battery capacity over days so I recommend charging this before performing. Nicely designed!
