It's a pretty nice 14500 light. The output is great, the anodization is top quality. I love the orange color. A lot of people complain about the UI, but I think it's ok.
The button is very mushy, which is quite irritating. The worst part, however, is the parasitic drain. The battery will die within a week of non-use. I've tested a few batteries, so it's not the fault of the included 14500 Fireflies battery.
I paid $24 for it on sale. I think that's about what it's worth. Nice, small 519A host with an included battery, magnetic tailcap, and aux light. Unfortunately, it falls short of a must-have light. Which is a shame given that the E12R and E07x lights are some of the best-in-class lights on the market.
