Btw, what's the "Kick"? Does anyone have a short explanation of what it is? I have no idea.
The kick is a drop in module made by Evolv for many 18... tub modes. It's uses wattage control like the Darwin instead of voltage for adjustment. The advantage is once you set it to a wattage everything you connect to it will be set to that same wattage. It uses a small screw on the module to adjust the wattage which is kind of a pain but once you get it set you really don't have to adjust it that much due to every atty/carto being set to that wattage.
If you use dual core regularly I wouldn't recommend it but otherwise it makes a great low cost solution for turning a tube mod into variable wattage, I use it in the Bolt, works great. If you want to go that route and funds are limited you could go with the Bolt now and be using it then save up for the Kick. You'd have a variable watt mod for around $90. Crystal Clear vaping has a good price on the Bolt that includes free shipping. If you order it be sure to pick up one or two extensions for when you get the kick.
