They're definitely not stiff! The description states that they are made of solid, high-quality carbon steel. Well, one of the 12 inserts I installed broke off when tightening with the supplied Allen wrench. Some of the others also had marks after being fully 3/4 plywood. However, they seem to be holding on quite a bit! I would buy them again. I would give it a 4.5 (round up to 5). Just be careful when tightening them.
