The coolest feature out of the gate is the OLED display. Does any flashlight need an LCD display? Likely not but it's still really cool and the form factor is so small while still being functional and legible!
The alloy body feels solid, the bottoms are clearly light plastic but I don't think that will be a weakness.
I'm not sure if the lens is glass/plastic but I guess that really doesn't matter either.
At approx $50 this appears to be worth the price, would defint be a deal at a lower price point. Not sure I would purchase if closer to $60...
