This is an excellent addition to my garmin computer. So many times I had to strain my neck to see what was behind me. Also, on narrow roads I often had no idea what was behind me. This is a nice device to follow traffic that is behind without having to use a rear view mirror that often has blind spots. So far it seems 100 percent accurate. I also am not that naive to make turn’s without at least a glance. This device makes my bike rides that much more enjoyable

Works like a champ! It "sees" cars long before I can hear them coming up from behind me and warns me they're coming. I'm in a rural area of Florida where the trees absorb all the sounds of vehicles behind you, so this device is perfect. Even with the cell phone screen turned off, and placed in my upper pocket, the app runs in the background and alerts you if there's a car approaching from behind. I highly recommend this product.
