I have only had one drop a way have a problem and that was because I was constantly messing with it and I stripped out a few screws. ( I like to tinke and change my set up.) The company has since changed the design and the rest is built better.

The muzzy looks complicated, but it really isn't. There are only a few moving parts and they are big and rugged.

The drop zone, trophy taker and trap door rest are pretty simular to most prong rests as far as parts and design go. And the quicktunes are just prong rests on a hinge pretty much.

The WB is a bit better in that regard because is has no moving parts. However I don't know that it is any more rugged, because if you drop it it can still move or bend.
