With extended use, the camera proves reliable — some buyers have operated it for years without major issues. The touchscreen display works flawlessly, and connection to the app via WiFi and the 4G module (UP04) is stable. Installation is straightforward, though routing the rear camera cable through the vehicle interior requires time. The rear camera has weaker performance in darkness, which is natural given its lower resolution. Some buyers noted the camera heats up in sunny weather.

Critical reviews are rare (1.8%), but they exist. Individual buyers reported focus errors or adhesion problems with double-sided tape on curved glass. One buyer noted the camera lacks voice messages and that the parking mode requires a specific UP04 cable. The wide angle of the front camera can create shadow distortion at the image edges.
