I got the Coolfire 4 mod a month ago after my aspire x30 (very square edges) had chewed through the pocket of my work trousers. Battery life is important to me & at 2000mAh this is lasting me a full day if not two of vaping comfortably. (I'm pretty hard on them too) it has all the features i need for mtl vaping although it can accomodate direct vaping the 40w limit may be an issue for thick liquids. The build quality is up there with the best & the ergonomic design fits well in the hand (i have little hands too) pocket wise its quite tall but it still fits well & doesnt protrude too much in that 'are you pleased to see me' kinda way that some mods can! The puff count too is a nice touch albeit a little scary when you see how much you've been hitting it! Looks great in black with my nautilus 2 tank. Definitely recommend!
