I ordered my guardian angel in the fall of 2019. I've been using now for over a year and a half, and the battery is still going strong. In rain, and dry days, the lights make sure everyone sees me. I'm living in a mid sized city, and traffic sucks daily, with these lights cars, SUVs and trucks give me a lot of space. I ordered the blue/yellow combo, I didn't want anyone to think I was pretending to be a first responder, and I have had a few ask me where I got the lights from. Of course I told them about Canadian Prepper's website.
The original charging cable is very short, and that is my only complaint. I was able to find a longer one though so it wasn't much of a complaint.
If you ride bike, get the shoulder strap mount as it keeps the white lights facing forward and the blue/yellow combo facing rear ~ no spinning side to side due to bumps in the road.
