Beware the sticking fire button on the Therion 166! They may have fixed the issue by now, mine was from a local shop, in Florida. It’s a known issue. I had to contact LV, who sent me over to Evolv to send it in for repair, they repaired it nicely, but less than 2 weeks later, it’s sticking again. Im not sending it in again, just being extra careful until i find a better mod. The button catches on the body of the mod with very little effort, just press a little below the center of the button and goodbye wick! Hope they worked that out by now.
