Review on CarThree 360° Bird View System: Waterproof & Seamless 4 Camera Car DVR with Universal All Round View - Super HD 1080P Night Vision for All Cars by Nick Nunez

In addition to the expected long shipping time from China. The product is amazing. I had a small problem and the customer service was fantastic. I tried calibrating manually without the calibration pads and it took a while, but it came close to what I wanted. I ordered the wipers because I plan on installing them on a couple of my cars and calibrating them for my truck and all I can say is wow I wish I had done that from the start. Lay out the rags, enter 2 measurements into the device and in about 20 seconds it is fully calibrated. I would highly recommend this product to anyone.
