First review: I haven't installed/used it yet, so I can't comment on its physical application yet. I was a bit disappointed when I opened the package to find that the black protective film on it was badly damaged and "peeling". For the price you really don't expect to get something in this condition. So keep in mind that you may need to put some kind of protective coating on it. Otherwise it would be a very secure ball mount in my first opinion. And I am very glad that a corner ball mount was suggested as the virtual mount is not suitable for my application.
