Review on 🚴 Ultra Bright Smart Bike Tail Light - Rechargeable, Auto On/Off, Waterproof LED, 30+ Hours Run Time (Seatpost+Saddle) by Shah Nelson

This is a pretty cool and compact design, but it just doesn't work properly. From day one the LEDs (battery, automatic function) didn't work properly which should have told me the future of this light but I didn't and now I'm sadly past the return window. At the moment it seems to be working but none of the automatic functions are working (sleep etc) and the indicator lights aren't working either so who knows. My personal experience is that he promises too much and REALLY doesn't deliver. Damn.
