Review on 🚴 BikeSpark G2-20lm Auto-Sensing Rear Light - Super Bright LED Bike Tail Light with Motion Sensing Deceleration Flash - USB Rechargeable - Water Resistant IPX5 - Made in Taiwan by Eric Basler

I would say I forget to turn on my tail light about 80% of the time when I'm riding my bike. I also often forget to turn it off until I get home. This product solves both problems. Came in nice packaging and looks good. I checked the brake lights manually and they seem to work fine with little movement as described. I am currently giving this 4 stars for two reasons. 1. There were no instructions. Sure, it's pretty easy to work with, but a little mini-page or two with instructions would be helpful for people like me who might accidentally damage the product by unplugging it from the seat connector to the clamp. This didn't happen, the plastic is very strong.2. I haven't used it on the go yet. If my friends say it works well behind me I will definitely come back and give it 5 stars. 90 hours of charging is also a lot of time and no battery is needed! Another nice feature.
