I have both! Really like them both. Im using a 18650 3000mah in the 3.7v. I thought I liked the switch on the GLV-2. These are fantastic! no need to press. Just barely make contact with it and it fires! One thing is you have to make sure some part of your hand is touching the switch and the bottom end cap to get it to fire. Wierd but pretty cool. You wont ever have to worry about it fireing when its in your pocket or somewhere else. It needs your touch! Pretty cool! Thanks Wiz. Ill be bringing both!
