The Acebeam K30-GT is extremely well built, powerful, and throws light very far. At low levels the tint can be pretty green and ugly, but this isn't a flashlight you'd be carrying if you didn't want a lot of light. It feels "safe" carrying this thing around, and it's sure to WOW anyone you show it to. The build is really solid, it's surprisingly small, and it handles heat really well. On high and turbo levels you'll wanna use the included handle, b/c it can get pretty hot (understandably).
The UI is very simple, although I wish there was a way to ramp down, instead of having to ramp up through all of the modes to get back to the lower ones. The batteries need to be taken out to charge and are a little bit of a tight fit, but it's not that big of a deal for me.
Overall, this flashlight is worth the money. It's mostly throwy, but it provides a large hotspot that allows you to see a significant area, and it's BRIGHT!
