Got one as a present, same as the one in the link. Its still in box will post when I get it fitted, I will connect camera to reversing light and hope it works. No rush as will be fitted to my next van conversion which is about ready for VRT. Will fit after that.
As everything cheap, make sure you do a bench test before start running cables, cutting, etc. If you can, set them at the distance they'll be just to make sure that you don't have any interference nor anything like that.
Other than that, they're very easy to install and they do make life easier.
Cheers,
