Well made, sufficiently strong for its purchase, price is fine. I use these to mount board material on a work bench. I have other types of clamps for other uses. You must really want the plastic caps (to avoid damage) A full metal clamp gives a better grip and position stability. The height of the upper clamp needs to be small to provide clearance for a disk saw. That height could have been a little less for me. I had a similar set, it was stolen, and after that I bought these.
