Ok, even I admit this is a bit creepy. Is it wrong to use products designed for the disabled to smash face in PvP?

Nah.

But it's still weird.



The Origin Instruments Corporation Sip/Puff Switch is a head mounted accessory used to actuate a two position switch by a simple sip or puff. It consists of a head frame with attached mouth tube and a switch box connected to the head frame by a second plastic tube. Sips and puffs are converted to switch closures inside the Switch Box.
