Review on 🔴 2 Pack of Volcano Eye Rear Bike Tail Lights - Ultra Bright USB Rechargeable Bicycle Taillights with Red High Intensity LEDs - Versatile Accessories for Bikes or Helmets - Easy Installation for Enhanced Cycling Safety by Seth Hogate

I ended up buying 4 of these, 2 for the helmet and 2 for the bike. They're very bright, easy to use, and work well during my hour of daily commuting. They are also easy to install and remove for charging. The USB connector is a little tight, but it charges. Haven't tried them in the rain or on long rides yet so can't comment on strength or durability. I like them mainly because they are very bright, not too expensive and I don't have to hesitate to turn them on every time I drive because they are easy to recharge. I use them in full flash mode and charge them once a week whether they need it or not. UPDATE: Downgrading my rating to 3 stars (from 4) because a light stopped working after two weeks. I think he was flawed from the start. While the rest works fine.
