The Wismec Active Mod is a mod like no other. Shockproof, shatterproof & waterproof. This IP65 rated device will outlast any other device in it's class.
It has a standard 510 adapter, so you can use your favourite tank with it. Also, a large 2100mAh battery will give you all day use.
Oh, and it has a Bluetooth speaker built in, for music on the go, and a carabiner to keep it safe and secure. What more do you actually need from a mod?
