Impact Atom Clamp with Ratchet Handle

I want to +1 the review that mentioned the weak link of this product, being the small screw that holds the whole thing together. I kept this at two stars because if you're not pushing this clamp to its limit, it should be mostly ok. For more info on that limit, please see the last part of this review. I've been looking for a post-mounting soltuion for my Inovativ EVO 36 cart, which I think has a diameter of 1.5. When compared to the Matthews MicroClamp and the SmallRig Super Clamp, this Impact Atom Clamp has the best grip - it wraps around just a bit more than the others (which both happen to share a design that's different from the Atom). The issue is in its build quality - the tiny bolt that holds this clamp together stripped completely after about a month of use. The most misleading part is that Impact states the weight capacity as the HIGHEST of the three (15.5lb, compared to 10lb and 5.5lb). I find this impossible to believe, given the inferior design.
