The whole thing works ok. Image quality is fine (not the best but acceptable). Microphones are useless but wasn't expecting them to be working on a noisy environment like a motorcycle.
My main issue is the way the whole thing is made. It assumes the "box" will be under the seat which is in the rear part of the motorcycle. My issue is that I have a Honda NC750x... absolutely no space under the seat for this (under the not really removable seat is the fuel tank!). I have a 20L compartment in front of the seat (where the fuel tank usually sits on another motorcycle). Now this is perfect for the box.. but the front camera's wire is then way too long.. and the rear one way too short. I ended up installing both in front... with the rear one pointing back at an angle... which covers my left blind spot but my legs and rear luggage hide the back.
Also, as one other reviewer noted, the remote control wire is attached to the box.. no connectors to disconnect (like the cameras) and it needs to fit where you want to route the wire.. which was fine for me but might be a big issue for other... The wire is rather large but flat... unfortunately the remote itself 3-4x times the width of the wire which will restrict placement.
I've also found that the indicator LED is completely useless outside when sunny.
Overall not too bad.. but at that price point was expecting more.
