It really depends from person to person, because everyone's opinion seems to be a little different.
But I'd definitely recommend it, the angles are great and you can pretty much vanish anything from a coin to a bottle.
It comes with 2 gimmicks, a small one, and a large heavy duty one. Honestly, I only use the big one, because you can use it for small stuff anyway, but it's good to know I have a back-up.
The only downside is the sound it makes, but don't let that influence your decision, it's nothing really, unless you're performing in a church or some quiet place.
I do think it's worth getting, if you're willing to put in the practice you can accomplish miracles.
