Tiny Sniper
When I pick up the Acebeam L17, I’m doing it for one reason: it throws ridiculously far for a slim 18650 light, with a laser-like hotspot. What I like most is the beam shape, people describe the TIR as giving a clean hotspot and a smooth, fading spill instead of reflector rings, and that matches why it’s my  favorite “woods walk” thrower

Reliable flashlight
I have enough throwers but I could not miss  L17. I bought it on ebay as used device just for hiking purposes, so if somebody breaks it, I will not cry much.

5 stars thrower
By far the best compact thrower, with a very, very strong beam and a silent switch.

My First Quality Flashlight
I have nothing bad to say about this flashlight. Just like the L19 it is flawless and I've been using it daily for nearly 3 years.
