I went to our local True Value yesterday and found the source of the drop receiver. It is a Master Mechanics brand. I own several MM branded tools such as combination wrenches sockets and such and have no qualms about their quality or durability. I looked over the other receiver inserts and noticed that out of the 20 or so on display only one other had a seriously tapered punched hole the rest not so much. Some of them were drilled holes not punched, there were also different prices for what looked to be nearly the same adapters, as well as different load ratings. What this tells me is knowing my bean counting partner like I do he purchased on price not realizing some possible quality differences. I usually purchase on appearances of quality not paying too much attention to the price if within reason.
