Does the job, but definitely get what you pay for. The threads are done poorly because the nut doesn't really stay on until you get it halfway down the threads. I had a thick enclosure and with the lock washer on the thing kept popping out. Only way I could get the nut to catch was to remove the lock washer and make a small countersink. Works well once installed, I have 5 of them running track and volume controls on a wireless speaker

These buttons feel very "mushy" and don't give any tactile feedback, and different ones in the same batch seem to connect with varying levels of pressure. Some of them have to be really mashed into the casing to get them to register, which isn't good enough for my project (a gaming peripheral). They were also about half the size I expected, but that's my fault for not paying closer attention to the drawings.
