I think it is great! Once you get the hang of it it will become almost completely natural. I had a little frustration at first, but now I will use it for a long time. I thought it was a clever method to the trick. With all the memorization it actually isnt that hard if u do it for about 20 minutes the let your mind rest for a while. After that you will get it almost every time.
