It ain't no Nikon, but I'm happy at $25.
I finally installed this camera and got a chance to use it. I decided that if mounted externally, the lens would perpetually be dirty and I was unsure if it is actually waterproof. So, I installed it inside looking out the back window. I bought a 15 foot extension and a double ended female connector (called video RCA cable) on eBay, so I can make a hook up at the same general area as the trailer plug connection.
The lens has such a wide angle that I found it hard to get used to using it to back up, but it works great to see who is behind you - much better than any rear view mirror.
For the money it works fine. We shall see how long it lasts.
