Review on POWERTEC 17205 3 Inch Polyurethane Casters by Charles Butler

Gently changes direction. I think it's because the outer shape of the gum isn't flat - it's like a donut, but the center is more pointed (don't know how else to explain). This worries me a little as the wheel barely touches the ground and over time it can leave a hole in the ground. If that's the case I'll see if I can lower my score because there isn't a good picture that shows it - a picture makes it look flat. I would prefer flatter wheels for heavy stuff. They are well fixed. A possible quality control issue: out of 8 panels, 1 was bent - about 1/16 inch around the edge. I had to use a vise to straighten it. This could be a Revain issue if it was a return and the original owner bent it. What is annoying is that the release lever is so small. It hurts, especially if you're wearing sneakers because you don't push the lever as hard and the shoes give out. I could keep a stick nearby to solve this problem.
