I purchased 2 of the duoclamps, and have used them very little, yet neither one of them now work. I'm very disappointed with these clamps, and though the idea is great, they were a big waste of money!

While I love every other type of Bessey clamp I own, these are the worst clamps I have ever purchased. The slightest bump to the rotating knob on the left side and they don't clamp. Every time I use them I have to make sure the black knob is correctly oriented, and then take care not to bump that knob.

I have six of these clamps in three sizes, and after limited use, they no longer engage and will not apply a clamping load.
