The 5 stars is my assessment of my entire order of this camera accompanied by HitCar RCA DC Power Audio Video AV Extension cable and a WishRing Wifi Car Backup Camera Realtime Video Wireless.  After opening and inspecting the packages I connected it up to 12v DC and ran a test using the Android App "WIFIAV".  My phone detected the new wifi signal, I connected, updated the name and password, and "poof", the rear camera appeared on my phone.  Since everything worked, I installed them as a rear clearance camera for my 34ft fifth wheel.  I mounted the camera high on the rig and ran the cable through the existing center top trailer clearance light and then along the inside of the ceiling in order to get the transmitter closer to the tow vehicle.  This was just to ensure I had a good signal.  Full install took about 3 hours, most of that was choosing how to run the wires so they avoided my wife's "ugly test".

The only downside, and this is my fault, is that the backup camera has the grid.  I didn't need or want that.

First unit didn't work as expected and the seller very quickly replaced.  New camera works great and I would recommend to others.  The picture quality is solid.  My only complaint is the mounting plate has slots designed for very small screws, when 99% of people will be mounting to a license plate bolt.

As advertised, would buy again.

Great customer services. Had issues with the first one I got and they sent me another one free of charge and it works great. I have two now

Video clarity is excellent.  Comes with a really long composite video cable.  Mounting bracket has four places to attach screws for many mounting options.

Honestly the best back up cam for the money. Minus the lousy mounting set up the cam itself is awesome and the night time quality it's bar none.

works great small and easy to attach.

Works very well

Works great very clean picture and wide view

Very happy  exactly what I was looking for.
