This little light packs a punch! It is very bright and I love that you can easily change the color temperature and overall brightness. If you're using it in daylight or in an okay-lit area, it won't make THAT much of a difference. But I think in more dim settings, this is perfect. It's also super versatile in that it's got different modes you can easily switch through... from police car lights... to club/party type lights. It's very portable and is about the size of an applesauce cup. I also like that it comes with a standard shoe that'll fit most any camera. It came already pretty close to a full charge, but I decided to charge it to full capacity before using it. I found that it operated continuously on 100% brightness for about 2 hours. It took roughly 2 hours and 15 minutes to charge the battery from it being dead. My only wish is that the magnet were stronger. The magnet works, but barely. I found the small magnet would cause the light to slip a little if you poked/touched it. But that's a small issue, as you'd probably be able to mount it on a camera or tripod. I used a selfie stick to hold the light as I got video of a subject. Overall, I'm happy with the light.
