I can only add what others have already said here. We've won two regionals
and been finalists twice since we started using it. Our robot last year had been thru two regionals, CMP and an off season event with hardly any trouble at all. We even won the quality award at one of the regionals. Its held up very well last year even with a sprung catapult in our robot. Its very adaptable. We've been able to integrate 3/4" square tubing, 80/20,30x30 and 20x20 into it.

Last years robot was the first we ever had that used the belt and clamping block system. The only down side we've had was with the plastic clamping blocks slipping on the frame and the nuts turning in their places in the blocks.
We ended up using the cams to keep them in place. On last years robot we used the metal blocks and they never slipped.

We've learned to keep a good stock of both 5/32 pop rivets and hex bearings
on hand. This year we bought a pneumatic pop rivet gun to make putting
the frames together much easier. Both last year and this year we also made
a practice robot with it too. We've made custom gussets where needed.
