All of the unknown name stuff comes from the same assembly line in china, if it looks the same, it probably is the same. No experience with this particular seller or exact problduct, but I did add a cheapo backup cam on my truck and couldn't be happier.
I already had a 10" overhead monitor with seeral unused inputs and outputs so all I did was buy one of the under $30 license plate mount night vision cameras and hooked it up. Been doing fine for almost 2 years including being swapped to another truck. Rather clear video and awesome night vision ability, looks just like daytime.
With this cheap Asian stuff, a nice wired setup can be had affordably. I have no experience with a cheap wireless setup, but have heard that they get grainy and pickup a lot of interference the further away you get( like mounting on the rear of a trailer).
