It was $37 on a sale. OK size and weight, really good battery life. EXTREMELY bright on high and adds a nice aroura around you on the ground at night. Like, its REALLY bright on daytime high, you'll get comments about it on group rides. I just leave it on high daytime mode to use the lights obnoxiousness as an excuse to sit on the back of pace line during group rides that are going a bit fast for my fitness. If you don't want to pony up for radar, this is probably the next best thing. It has an internal accelerometer so it senses braking and big bounces and lights up very bright and steady.

^^ On the subject of lights, I'm running these and have been very happy with them. They've survived rain and snow, commuting, gravel rides and races and all the general abuse of being on the bike 24/7 for close to a year.
