I purchased these sockets and when I received them they had two 1 7/16\" sockets but was missing the 1 1/2\" socket. I contacted the seller through Amazon and the responded promptly. Once I sent them a picture of what was wrong they were on it. They told me it would take some time because the single socket would come directly from the factory in China and it did take a few weeks partially because of the holidays but it finally showed up and all is good. The seller was constantly updating me on the progress at leas a couple times a week, so great customer service! I have used the sockets multiple times now and they seem to good quality so far, time will tell.
