Review on 🚴 BLITZU 2 Pack LED Safety Lights for Bike, Kayak, Dog Collar Leash, Stroller, Walking, Boat, Runners, Night Running - Shoe & Wrist Clip-On, Strobe, Warning, Blinking, Reflective Light Accessories by Matt Watson

These are super bright, small, durable clip-on strobes. They lasted quite a while with the included batteries, but the tiny screws were too far out when changing the batteries. Also for this user with very high fine motor skills. After the first battery change, I threw one away in desperation. I've managed to change the other, but it's a difficult exercise. If only there was an easy-to-open clip design or they were rechargeable. I've tried, but would pay significantly more for a better battery swap/charge. Otherwise they were very bright and otherwise usable. Just not permanently.
