I bought this because I wanted to experiment with a bit of percussion whilst playing semi-acoustic sets.
I was quite happy with what I bought. It fitted well to my shoe and rarely slipped of - only really when I thumped very enthusiastically.
The Sound was alright. To be fair this is not a full tambourine so it'll never have the best quality sound; but it still lacked some of the beef I was hoping for. But, over all it as still quite good and is still very handy when you've no hands free and want to give a little percussion.
Fits snugly on your shoe and definitely won't come off. Ideal for solo guitarists, a two piece band or for percussionists playing cajon. Sounds really nice and bright without being too overpowering. Easy to control the volume. Though I would say it does have the potential to be loud enough to be heard in a pub band two piece situation.
