Jeff did reviews on a couple of their products and they look pretty good. The chrome appears to be nice and they are affordably priced. Only time and usage will tell how good they are. I had Mac, Matco and Snap-on swivel sockets in the past. The Mac and Matco sockets would loosen up and get floppy in a relatively short period. Their sockets had hex head screws in the joints. Tightening them did not alleviate the flop. The Snap-on were the best in my opinion and stayed tight even with heavy use. They have pins that are driven in and ground flush. My current swivel sockets are USA Craftsman. They have held up surprisingly quite well. I have yet to break one. They have gotten floppy though. A couple of the sockets have roll pins and the others solid pins. I actually have a 1/4" 12mm Craftsman swivel socket that I had to use a 3/8 ratchet for a specific situation and amazingly it didn't break.
they will all loosen up I just use a o ring to make them stiff again. I am gonna start using them this weekend. I will do a updated review in few weeks.
