As other reviewers have noted, this is not a 3" clamp, it is a 2-3/4" clamp. The clamp I received has the fixed jaw tilted to one side, about 5-8 degrees. I expect this won't matter much for regular home projects, but for precise gluing, a clamp like this will put lateral pressure and potentially dislodge parts. It's not an expensive clip (a comparable HFT device costs less than half that), but it's certainly cheaply made.
