Got this light as I needed to clip it on a saddle pack strap when bikepacking. It needs something to stop it sliding off. Also I find it very fiddlely getting the mount on a seat post. Otherwise it is a beautiful light. Incredibly bright and so easy with the magnet to get on the mount
Love these lights! Just bought two pairs so that I never run out of charge (I bike A LOT)
Walk - Bike - Run — with this lightweight but considerably Bright Light whatever I am doing out on the road I know I am going to be seen.
You can switch one unit around for whatever activity you are doing. Or they are reasonably priced enough to get several.
Also a good add-on to a safety vest 🦺 when you are working in a setting where you need extra visibility.
Super small, super bright, super easy to charge!
The Plus Rear bike light has a convenient magnetic base which has proven to be strong enough to endure rough descents on a hardtail MTB along with a good variety of flash patterns and brightness. The charging capability is very convenient with the integrated USB design as well. The only thing I'd say could use improvement would its fluid rejection capability - I had one unit fall into my pint glass on an occasion and while it still sort of worked, it mostly stopped functioning correctly after the submersion even once fully dried.
