I'm trying to get these, two in black and one in purple.
These are the original VTC versions. I have one silver and one purple. I also have a black in the pro version which looks like this.
I only got the mod in black since I have plenty of tanks and they look identical but the newer version has some fancy newer features which I don't use and the battery life is only about a third of the original version.
I know it's not a super fancy mod like most people enjoy but it's the kind that works for me. Once I find something I like, I stick with it until something better comes along. The Pro version is probably better for people who would use all the features but I don't, I adjust my wattage between 20-30, down to 15 when starting up a new coil but that's it. That's all I need.
