To begin, I give the seller - Team PlayBetter - a lot of credit for being early and putting a personalized message in the package. A nice added touch.
This was a bit of an impulse buy for me and it’s easy to feel guilty about it since you can buy a mirror for about $10. Having said that, it is awesome! I write a lot on country roads and so having the awareness of what’s approaching has been amazing. I’ve used it about a half dozen times now and haven’t found too much that I don’t like.
Performance wise, it works really, really well. It picks up cars as advertised about 450 feet away and while I haven’t reached the maximum eight I have had six cars on my screen at once. The audible alerts are loud enough to catch my attention regardless of my speed and having the high-speed alert is a nice feature as well. I use it with my RidewithGPS app and it is seamlessly integrated. Battery life seems solid as well. It has become and will remain an indispensable part of my rides going forward. My only ding on it is that it’s hard to integrate with a saddle bag since that’s the install location. Solvable and so mostly just an annoyance particularly given some of the huge benefits outlined above. Well worth the money.
