I really like this light, and I wanted to share my experience because it is a great device for forgetful/distracted people or those with ADD/ADHD. The light is very bright and appropriate for my use and my forgetfulness. It fits exactly as presented in the pictures. I noticed another review complaining about the installation, but I didn't have that problem. It was super easy to install, and no tools are needed.This kind of smart light is exactly what I wanted, as they turn on and off automatically. No more forgetting! With my old cheap traditional light, sometimes I would forget to turn it on. If I remembered to turn it on, sometimes I would forget to turn it off at the end, so it would be dead the next time I wanted to ride, and replacing the batteries was a bit of a pain. The traditional light I used before was fully discharged after storing my bike during the winter, and the batteries leaked and ruined the light. In contrast, this smart light is easy to remove for charging, so the batteries don't have to endure my shed's harsh conditions.Charging is a breeze: I just plug it into the same charger (no charger included) that I use to charge other devices. Of course, my challenge now is to remember to leave it charging, but at least that's only one thing I have to remember :)Besides being bright, the light is smart. It will sense when you are moving, and stay on for a while when you stop, let's say at a crossing. At night it stays steadily on, and during the day, it is on and flashes intermittently. The brightness also varies according to the current conditions. I also like the flashing yellow lights on the sides. They are small, so I wonder if they are really visible, but regarding safety, every bit helps.To be frank, it is not cheap, but I paid the premium price for this light because I think that my health and safety are worth it.My only complaint: the light is a bit wide and thick, so it doesn't leave enough room to charge or plug another device next to it. I have a charger with 4 USB ports, so in theory, I should be able to charge 4 lights simultaneously (I have two bicycles, and I also have tail lights.) However, the light is a bit thick and wide, so my charger can only accommodate two lights at the same time. However, it's a minor issue.

The mount included in this package did not match the one shown in the description, which is the "headlight mount" that is supposed to be included in this package according to the manufacturer's website. The mount included is for a taillight, which is impossible to use with the strap included with this item. As a result, it was impossible to mount this light with the parts provided.
