Integrates well with my roam head unit. Alert is just the right volume. Plenty of time to adjust my road position before the car arrives. the best application is when you are out by yourself or with another person. If you are part of a large group it will pick up the riders behind you.
The item itself is nice but the shipping process was not. It took 2 weeks for item to ship and I had to reach out more than once to see what the hold up was. The item was on back order but it never said that when I made my purchase online.
