Review on CarBest Sensor Traffic Microwave Detection by Josh Sharp

First of all, there are no precise instructions for installing the hardware. the documents contained in the box and the labeled parts are ambiguous and written in Chinese (the characters of the language are unfamiliar, so this may not be correct). Fourth. The rating of a "professional" installation is unrealistically low. Fifth, there seems to be no way to contact the sellers of the product for answers to questions or clarifications. I would recommend anyone thinking of installing this unit themselves to get a copy of the available instructions first. I'm seriously considering returning the one I have. for a return.
