The camera says waterproof but the unit is so cheaply made that the screws that hold it together were not secure and stripped.

and I secured the screws on the size as tie as it can be and it still moves

The screws that hold the camera body together have come loose, and the screws for the angle adjust are loose and will not tighten.

My unit was missing a screw on the bracket, and the screws that are on the bracket do not actually tighten properly, which causes the camera to vibrate when driving, making the guidelines not correct, and the camera slightly undependable (down to the inch when backing up)

The mounting screws seem a little wimpy, but they seem to do the job

The only negative would be the mount, it works but there is not a lot of options and the screws for the mount were not very secure.

So, I grabbed a small Phillips screwdriver to first test and see if the screws were just loose and needed tightening.

the screws rust

The screws that came with the camera are pretty weak

Some one complained about a loose Screw when shipped
