The set-up, installation and pairing to my head unit was easy and as advertised. The radar works well, I wish I had purchased it earlier.
More safety with motorists is a real good thing! I almost bought the Garmin version a while back since many of my riding buddies liked theirs, but when I heard Wahoo was coming out with this radar unit I decided to wait and match it to my new Wahoo head unit. Setup was very quick and easy. Battery life is excellent and the radar is very accurate. Of course I still use my sunglasses mirror for busy SoCal streets, but when you are flying downhill it's nice to know you can take the entire lane with no cars behind you. Yes, it's a bit pricey, but your safety is always worth it!
I've had this for about a month now and ridden with it at least 20 times. While I wasn't sure I really needed it when I bought it, it has become almost a necessity now that I have used it. I am a senior rider (78 years), and it is wonderful having the few seconds of extra notification of a car approaching from behind. It gives one sound when a car is approaching, a slightly different sound when a string of cars is approaching, and a different sound if the approaching car turns off at another street before passing you. It also has a graphic display on the Element Bike Computer which changes color from green to orange to red as the car approaches. We have a lot of younger (almost everyone is younger than me now days) riders who are very capable (fast) including a fair number of pros (Boulder, Colorado), and the Trackr also alerts me when someone on our many bike trail is approaching on a bike. While I always double check with a mirror, this is a necessity at my age and probably useful for younger riders. The only issue I've found is riding a bikeway that parallels a highway (such as the one along US 36 from Boulder to Denver). The unit kind of goes crazy (constant beeping) in that situation and I have had to turn it off.
