Review on 🚴 OTYTY Bike Tail Light with Turn Signals | USB Rechargeable, Ultra Bright LED Safety Warning Brake Rear Lights | Wireless Remote Control | 4 Modes | Waterproof | Suitable for Mountain Bike, Road Bicycle by Brendan Thorpe

This is only good if you superglue the device to the attachment point. It's designed to slide off, so you'll have to go back to find it every time you hit a bump in the road. Automatic switch off function. Maybe it works. It always seems to stay on. Sometimes the lights go out in the middle of a ride, which is scary if you have to rely on it (and don't use hand signals). Batteries can no longer hold a charge after a week of use. So you'll need to charge every half hour for up to two hours of use. I only used it for turn signals, so it really doesn't even last for half an hour of driving. Once you've glued the item to the mount, you'll have to reload it in a very cumbersome way.
