I feel a lot safer riding with this unit. The only time it doesn't pick up traffic behind me is when I'm riding on a bike path separated from the the road by large concrete barriers (it will still pick up taller vehicles in those conditions). It will still pick up traffic several lanes over on the same separated bike path, so I'm not sure how wide of a view the radar has, but it picks up everything. I like the alerts it gives me on my Garmin computer (I haven't tried it with a phone or other GPS brands).
I thought after pressing the buy button that this was one of those silly clever, but useless tech purchases that would end up in my dustbin of gadgets. However, In conjunction with my ELEMNT Roam 3, it provides me with a measure of safety I just didn't expect. The TRACKR not only alerts you of oncoming vehicles, it tells you how many, how close, and when the coast is clear. I wasn't sure how the brake light aspect worked until I was behind another TRACKR user and darned if that didn't work too! Safety is priceless, but at $249 the TRACKR is a bargain.
A lot of my friends have the original and 300 Raveman, but I just didn't think they were bright enough for daylight riding. The 500 is the answer!!! Super bright with 2 large LED's with side exposure. I'm sure it would be fine for night riding, as well. The Garmin mount works perfect, both to the stem mount and for the Garmin on top. It's super light (a fraction of my old Bontrager light) and is easy to charge. I can get 2 - 3 long rides in without charging (probably plenty of charge left). This is a winner!!
These lights are small, lightweight, and versatile. I've got several. The rear one is the best I've found for my aero seat posts. I pack a set in my bag back-up. The light and its holder weigh 3/8 oz on my postal scales. The two rubber straps for my aero seat post weigh 3/8 oz. Rechargeable and good for a 7 hour ride.
