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.
appreciate the Cutoff Beam-ground directly in front of me stays lit, but beam does not blind oncoming riders(when on multiuse paths). Note, the attachment clamp is not a quick release, it requires a small hex wrench(provided). This is not helpful if you want to remove the light when you are locked up, but is helpful as it would slow down anyone who was trying to grab it quickly. But it can also make charging the light a little more difficult without removing it.
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!
The light is a bit heavy compared the to the Light & Motion light it replaced but the battery life is the best I've ever had on something this compact. Most of my riding has been during the day so I'm only using one of the flash modes most of the time but it's been over a month and it is still reading in the green. I might also have about an hour of use on the low and medium setting after dark so really it is very impressive, wish I kept track of the actual time. The light is solidly built and I like the mounting system, no slippage at all and I do ride on some terrible roads. It is bright enough for me, there might be some washout as the other reviewer mentioned but it hasn't bothered me at all, for the price this has to be one of the best available.
