Since everything is a square block with reinforced plastic, it does not dig into shoes, etc, and I like it very much with pop design. Next time I think I would like to buy again. I changed it because it was a metal design to dig into the shoes such as MTB. I used a double-ended pedal wrench TMC which I purchased again with this tool again. Huge force is running and accuracy is good, so can not it be with professional use? I think whether there is something useful if there is one.
