Look it up.
The reviews say it's pros and cons so:
Is it your style?
Do you mind having to wear the gimmick?
Do you do a lot of mentalism?
Would it be something you use a lot or just occasionally?
We can't tell you if you should get it or not. You have to decide on your own. Please just look up a review(there are plenty) and decide for yourself. Don't involve the entire Theory 11 magic community...
Hope this helps,
