This is an excellent little light. It came pre-charged. I've used it for a week so far, and it has not needed recharging yet. It's quite bright and has some eye-catching patterns. With the hardware, it clamps securely to a light strap on my backpack. Without this hardware, it sometimes falls off if banged around a lot. I'm sure for most people, it would stay put. It is lightweight and doesn't need heavy AA batteries. The charge wire is a convenient size. I have had multiple clip-on and mounted rear red lights for cycling, running, and scootering, and this one is among the top choices. I honestly have nothing bad to say about this light and would recommend it to anyone. I with these came in clear or amber to use on the front of the scooter.
