Review on 🔦 FANCYWING LED Cycling Saddle Bag with Reflective Turn Signal Indicator Light - Lightweight, Waterproof, Safe for Nighttime Bike Riding by Josh Reynolds

This would be a great bike light but I felt it could not be used as intended. The biggest problem is that it turns off after about an hour. At first I thought the battery was dead, but found that I was able to turn it back on. It's not practical for me to use it if I can't trust it to flash when I'm driving for more than an hour. Others report that the battery doesn't last long. Why didn't they design it to use alkaline batteries? I found another similar flashlight from ECEEN on Revain that I bought that seems to work better. In addition, the design of the charging port allows me to connect a cell phone charger, so I don't have to charge it as often.
