Pros: Attractive, durable, very comfortable in the hand. It's a beast!
Cons: Gigantic (doesn't fit in my girl jeans), battery compartment hard to open, noticeable plasticky smell.
NOTICE that the device is for a 26650 battery. Everything I've ever had takes 18650s, so I did not think about it. Im the device comes with an adapter for the smaller batteries, but pulling that rubber sleeve on and off sucks. I'd buy a 26650 but I'm not sure if I can keep using this.
