It does what it is supposed to. It projects the digital speedometer onto the windshield. The instructions have very small print, and its a little complicated, but its a good investment. (You can easily find the instructions online as a PDF file) The sheet of reflective film that they give you is very noticeable from the outside, and might land you pulled over for obstruction of view, so what I did was put it in back of the registration sticker and its not very noticeable now. The OBD2 cable is long enough to reach the destination and its eaay to tuck exposed cable into underneath trim. The slip resistant sticky mat lives up to its name, but the cable and multifunctional switch are located facing the windshield making the switch very inaccessible if you want to change a setting, and nay require removal from the mat in order to navigate. Thats the only thing I see as an issue, the switch should be on the side facing the driver, but I only intend to use it as a speedometer, so it works for me.
