I don't use it because I can see my hitch. Otherwise I would use it.
I like it. I like the looks of it. It's also a good conversation starter. I've had several people approach me when I'm outside and ask what that is for. Others know what it is and just ask if I like it / use it. All have said they think it is a good idea and wish their brand would do the same thing. Some may just be too nice to say otherwise, though.
I do wish it were actually a camouflaged door into a small storage area. Maybe for water hoses.
By the way, at a dealer's we saw another Keystone product (Cougar) with a similar mirror. It also had some funky lights next to the mirror. I'm not sure what they were for. This picture is from the Cougar brochure.
