I love how it sounds. Very big, clunky sound (audio sample is spot on) that instantly transports you to some far away land (if you're European). You don't even need to play a groove for it to sound awesome.
I fear for it's durability though as the dried shell/seed casing it's made of look quite brittle. Not really the fault of the manufacturers though, I'm assuming you have to use these materials to get this traditional sound, so don't throw it in your bag with anything heavy.
