Got my Pulse today, already ripped through a bottle of juice on it...I like this mod. The switch is kind of interesting because you don't need to bottom it out for it to fire solid, it seems to give full power about half ways in. The bottle is a little bit of a challenge for me to maneuver while refilling, fat fingers and all, but it'll do. Can't wait to find some replacement bottles in stock somewhere, because this one is a keeper. When replacement panels and spares are well stocked, I'll be grabbing some different color panels and bottles for it. For a little less than fourty bucks, it's a real winner.
