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 Aaron Franklin

I've been wearing Bitzu blue safety lights for my early morning runs for a few months now. They've worked in both rain and severe frost, and so far so good. The backlight can be switched from constant to fast and slow pulsing and can also be easily attached to clothing, be it a belt or jacket pocket. Visibility and headlights are excellent. The only drawback is changing the battery. There are four tiny (TINY!) screws on the back that are barely visible. In order to see the screw heads, you practically need a magnifying eyepiece from a jeweler. Also, I can imagine that at some point they will need to be removed as they are tiny and although a tiny screwdriver is included with the light, this procedure does not help smooth operation. ** I strongly encourage you to reconsider battery design/availability. I highly recommend this product!
