Review on 🔦 Cincred Bike Lights: USB Rechargeable Front & Back Bike Lights with 8+ Hour Runtime and 400 Lumen Brightness - Perfect for Night Riding on All Bicycles by Cody Johnson

Update: The button issues got so bad I had to turn the light back on. Don't buy it - you're just wasting your time! Once you've put it on, the light is good: it's quite bright and seems to last (although I've had it for a few days now, so only time will tell). tell). It looks like there are two modes: always on and a weird irregular flashing pattern. The problem is that the button is unusually temperamental and there doesn't seem to be any understanding of how to toggle it on/off or switch modes. I've wasted precious minutes of my life cursing this thing and trying to get the button to do what I want, and I regret not wasting it on that.
