Fantastic! I have a happy hand truck story.

I use a 2 wheel hand truck from Clipper Products. Mine is very similar to this one:

They have lifetime warranties, and about every year and a half, one goes out on me, luckily in a way that I can use it for the gig. I have a spare at home. Clipper has always repaired them for me, just charging me shipping which both ways is $20.

One just broke completely after being in service for about 5 years, and Clipper is sending me a brand new one.

The Rock 'n roller looks great, but the Clipper fits my needs better.
