Wouldnt ride solo without it.
Functions well and gave adequate warning of approaching cars. Would periodically lose contact with head unit (Elemnt Bolt) but would re-synch after a period of time.
Love having early warning of approaching vehicles from behind.
Allows you to know when a vehicle is coming up on you from behind without the dork factor of a clip on rear view mirror. Never had it miss one approaching.
I have gotten to really appreciate this product on my road rides. Its like having eyes in the back of your head and the flashing light by itself is excellent.
The light is the greatest thing ever. The mount is the worst mount ever. Garmin's mounts are never that great. K-Edge needs to come to the rescue.
I bought this to help when commuting. I know I could have bought a mirror but tech is so cool. Also helps when doing fast long descents I can glance to see if cars are behind me.
