I have several 15mm rod clamps with 1/4"-20 threaded holes and this is by far my favorite in a couple of weeks. I have a feeling it's going to happen comes at the worst possible time with the SmallRig version too. Not this one! Will it last?' whenever I pull that out. I thought all tool/frame maker products were pretty much the same. Lately I've come to rely more and more on Camvates .Decent price but most importantly they are reliable..Not always perfect but reliable.5 stars.
