Very sturdy in construction, the paint cracked straight down to the metal and is peeling, the jaws have a deviation of 1 to 2mm resulting in tightening first on the right and then on the left. It doesn't make a difference on metals, but it's a bit of a problem on plastics and fragile items. It has screws but is not adjustable, it's a material failure. I might have gone for a (smaller due to price) Ridgid Matador if I had known, however, with a little patience I believe it can be fixed.
