Review on 🚦 Cygolite Hotshot Pro– 200 Lumen Bike Tail Light [HARD MOUNT VERSION]– 6 Modes for Night & Day with Adjustable Flash Speeds – Compact Design– IP64 Water Resistant– USB Rechargeable– Ideal for High-Traffic Roads by Jason Vigil

This is actually a great light that makes you very visible. Ideal for commuters and possibly racing cyclists. Unfortunately, the fastening system for the fixed-mount version doesn't hold the seatpost very well and occasionally moves the light off-axis even when fully tightened. I was recently riding my bike and somehow the light fell out of the mounting clip and I lost it. I drove during the day and didn't realize it until it was too late. I'm also very confident that I installed it correctly and heard a click when the light was properly attached. It's a bit of a shame because I really liked the visibility this light offers. I would buy another one if I could, but unfortunately I don't trust the attachment system enough not to lose another one.
