Review on USB Rechargeable LED Safety Lights (2 Pack) - Clip On Strobe Running Lights For Runners, Joggers, Walkers, Kids, Dogs, Bike Tail Light Reflective Gear Accessories by Chris Elam

Update #2: After some switch issues on two lights and a lower review, Amy with Keywell contacted me to send replacement units with improved switches. Fantastic customer service plus the new switches feel much more positive. These lights are now perfect for me.Update #1: Switches on 2 out of 3 units have pushed in after only a few weeks of use. The lights still work but are very difficult to switch on and off, esp. with full-finger gloves. It's a shame that such an otherwise great product has such a basic flaw.Overall: Exceptional lights. I wish I'd come across these first. I cycle 2 hours a day in the dark. I clip these on my socks/cuffs depending on the weather and as extra lights on my backpack.Pros:* Very compact, smaller and less weight than other rechargeable clip-ons I've used* Long lived (I get at least 6 hours of blinking)* Super bright* Convenient on/off/mode switch, no need to hold the switch down for 3 seconds to turn on and off* Only three light modes: steady, blink, and SOS. Two clicks and I'm blinking. Another two clicks and I'm off. I don't need to cycle through three speeds of blink and three levels of steady brightness.* Easy to use, secure clip that you pinch between your thumb and finger like an old-fashioned clothespin (other clip-ons I've used have overly tough springs and awkward clips that are nearly impossible to use with summer gloves on and that actually break)* Micro USB chargers are everywhereCons: None yet.
