“This thing is bright! I like that you can easily choose the brightness. I’ve seen others say it’s heavy. That’s the feel of a metal flashlight in your hand, not plastic. The size is great too. It’s small so you can pack it away easily. The only drawback is that it does get hot when you run it at its brightest. But if you need to use it for a long time, just knock it down one setting and it won’t get as hot. This is by far my favorite flashlight!”
