UD TEC Mod
The TEC is a simple, fully mechanical 510 threaded MOD. It is compatible with most 510 threaded atomizers, cartomizers, Joye Ego atomizers and Vision Ego Clearomizers. The switch is mechanical and located at the base of the device. The collar on the switch assembly can be screwed down to lock the switch and prevent accidental discharge. Multiple vent holes have been punched in the tube for added protection.
