In full disclosure, the effect does work. However, as mentioned is does require the purchase of an additional phone app. That raises two questions. Why do you have to pay for the app if you purchase this? And what this this purchase get you? To answer the first question, the app does all of the work. This purchase will get you very little. It merely provides you a couple of jokers and a couple of gaffs that you probably won't need if you own of the of other available decks that this works with. This purchase doesn't even include instructions or routine ideas. So if you want to use Bicycle cards with non-standard Jokers, buy this. Otherwise go straight for the app and choose one of the other supported decks. As far as the app goes, it does work but it is very rough and so obvious that even children will know it is an app. I wouldn't say that it makes the effect worthless, but it's not nearly as hard hitting as I had hoped. It's more of a gag than a magic trick. I wish that I could take back the $18 I have invested in this trick and put it into something else. I feel quite let down.

I really wanted to like this, but potential buyers should be aware that the ap doesn't work with the latest iterations of iOS or Android, and that ProMystic has no plans to update it.

Been getting huge reactions with this the past two days. Almost don't want to tell you guys...this thing is so good...

This is a great trick. People love this effect.
You can go wrong with this. Grab your smartphone and perform it easy and clean.

Purchased this and loved it . Sadily it is no longer supported by the iPhone app not comparable with IOS 11 only IOS10
along with some others favourites.
I am told by promystic there are no plans to update the app as
Apple want to much money.

Not sure where the first reviewer is coming from. I work at functions, weddings, parties and this always blows everyone away. The fact you get it wrong and then a card freely in a camera view morphs into their card and you can move it around to a layman is mind blowing. Done this 100's of times and it has never failed to kill.
Would have paid £50 for this. How many disappointments have you bought for a lot more than this even with the app.
