Q&A: Any experience with the Harbor Freight aluminum bar clamps?

Hello all, I am new to this site, and fairly new to wood working. As they say, you can never have too many clamps, and I find myself picking up a couple of new ones with each project. I typically stay away from Harbor Freight, but I’ve heard good comments about thier clamps. Have any of you had any experience with HF clamps and more specifically with thier aluminum bar clamps?
