the sounds are all pretty realistic, althoughif you hit a pad really hard, the vibration somties sets of other pads, althogh this wont be an issue if you tighten everything up.

it hasnt fallen apart yet

Overall this is a good buy. The only other problem iv had is that when you play without headphones, the stick on the pads make a lot of noise, but i get round this by putting rubber bands on the sticks
