I wanted something smaller that looked good on my smaller 650mah batteries. Kanger Mini Protank 2 fit the bill quite nicely! If you feel like being fancy you can deck it out with a nice drip tip but the one it comes with is top notch. Pros: - Looks amazing on an eGo battery. - Hits about the same as a Protank 2. Maybe slightly less powerful. - Great flavour! - I prefer the draw on the mini over the ProTank 2. - Drip tip is removable and fits very nicely. Customization! - Quality parts, stainless steel, pyrex glass. No glue. Cons: - Coils only seem to last me about 2 weeks even with frequent cleaning. It's still pretty cheap but I am frugal! - Smaller size tank 1.7ml, needs refilling more often.
