I am giving it 5 stars
Bought this camera for my 6month old. Product installation was not difficult. The most time-consuming part was to hide all the wires underneath the panel and seat. It was not bad. I was able to get it done under 20 mins following the instruction that comes with the package.
The display can be installed via a sticky mat that comes with the package. When not in use, it can be folded down flat. The display is very bright and non-reflective. I took a few trips on a bright afternoon. I was able to clearly see the monitor. (my dashcam camera display in my photos, on the other hand, was less visible due to its brightness and screen reflectiveness).
The baby camera is very small and lightweight. It is strapped at the seat headrest. The strap belts are way too long for my car but it can be easily adjusted. As long as the camera is strapped tight, there will not have any vibration during my 20 mins drives.
I am giving it 5 stars for the limited time I had with it.
