If you've got rock band 3 and you like playing drums this is a must have. Pro-drums put a smile on my face on medium and I'm not even the drummer in the house.
Easy setup, quieter than the drum pads even with the first party silencers. Construction quality is good justifying the price tag. Bought it for my wife, she loves it
Might not be a con but it is something to think about. Extremely rapid strikes on the cymbals don't register in the rock band 3 freestyle drum mode. Not sure if this is the game ignoring the inbetweens but I'd guess the shock sensor in the cymbal...
