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 Mark Powell

I like this device because it has 3 different flashes. I use a walker and the sidewalks are in poor condition, forcing me to be on the side of the road with better coverage. In some places there is no light. I attached one device to my shoulder bag compartment and the other to the front of the bag that hung on my walker so cars could see the pink light coming from behind me and coming toward me. Works very well. The only thing I would like to improve is to eliminate the micro screws to access the battery and have the back thumb up and down like my phone. I am glad that I bought this product.
