This is pretty much junk. Don't waste money. I noticed that after a few months they started to rust badly and now (about a year later) they look terrible. They are almost completely rusted. This is silly as a product intended for outdoor use needs to be rust resistant. Also the key they give you is quite annoying. It does not include a Β½ drive but does require an 11/16 socket. Now I have to carry an extra socket and breaker in case I need to change tires. It would be advisable to fit a ΒΎ hex so you can use a standard mount with it. I don't know if this is an extra layer of security, but it's annoying. If it comes down to it, don't buy it unless you need rusty nuts in a few months.
