Review on 🚲 BikeSpark G3-35 lm Auto-Sensing Rear Light: Super Bright LED Bike Tail Light with Motion Sensor - USB Rechargeable & Water Resistant IPX5 - Made in Taiwan by William Anacker

Product update 1 year after purchase. This worked very well for almost a year. Then it stopped working. Doesn't respond to buttons, loading or anything. So I have to change my rating to 2 stars. First Review - I've had this light long enough to use it for just one day. I like the features - auto start, auto stop, auto brake, dual mounting systems and so on. But there is no guide for it. There is no video of how to use it on their website. I contacted the company and they sent me the instructions in a text email, not a .pdf. They said their intention was to make it intuitive enough to not need instructions. But the instructions in the email allowed me to learn many more features that I was previously aware of. I suggested they provide some instructions for the user. Everything seems to be working fine so far.
