I just received this a couple of days ago, so I cannot rate the battery life. The light is lightweight and puts out quite a bit of light. Love the light on the side. It's very versatile. Of course, the rechargeable battery won't keep me running to the cupboard for more batteries either. It'll be a perfect addition to my gear in our motorhome. I'm already thinking about getting a second one of these.

I have a few flashlights made by Klarus so I know the quality. I am very happy that they honestly describe the lumen output, unlike many companies that have absurdly high output claims. Klarus claims 800 lumens and I believe them. This light throws a nice tight pattern for the beam. I appreciate the USB C for a faster charge instead of the micro USB.

This is lightweight yet feels rugged. It is not too heavy for even a child to carry. There are clips for a shoulder strap but one is not included. The sidelight is also very nice and can be a white light, red light, or a flashing SOS red light.

This can also act as a power bank to charge your devices.

Maybe Klarus will come out with a model that has a much brighter output and more battery capacity. That would get my interest.

This would make a great light to take camping or just keep around the house.

I like it and am happy to have it.

A must have for emergencies! This light is built tough! Feels like it’s made out of military grade abs plastic. Lights bright and shines far, and the belly light is awesome and very handy. I’d probably pay 100$ for this thing it’s that good!

I thought this would be a cheap flashlight, one suitable for kicking around in the garage but not much more but it's actually pretty decent.
Nice Li battery in there, decent capacity and simple on/off switch, no complicated 'interface' for once.
Not super expensive. Holds a charge for notable time, even in an unheated garage. Good throw.
Nice flood from the belly light. Pleasantly surprised.

RS 10 flashlight performs as advertised!
So pleased to have purchased it.
