Review on OEMTOOLS 25567 21MM LUG SOCKET by Bryan Covington

This bit is said to be for use with flare nuts, but its design has probably not been well tested. They do their job but my nuts get stuck in the socket every time. Not sure what the problem is because I have 21mm nuts, but perhaps something could be engineered into the socket to prevent the socket from getting stuck? I have no idea, but I've found that expensive/high quality sockets like Snap-On don't have this problem.
