I just got this kit in today. It has a 400 mah battery with 1.5 ml refillable pods. The pods are 1.8 ohms. You charge it by plugging the end of the battery directly into a usb port, same as the rock by boulder. So far, I am really liking this kit and it is cheap!! You can get the kit for around 13 bucks and when you can find the pods, you can get them for around 10 bucks for 5. I dont have any idea yet how many refills they will last, I assume it will be what kind of juice you use. The draw is a bit airier than I prefer. I was hoping for a myjet like draw. So far I have used 50/50 18 mg tobacco juice and level up tobacco 24 mg. I did put a piece of tape over both air holes on the side and that does give me the draw I like. I do not know if that is the safest thing to do though, does anyone know if I should do that or not? All in all, i good little cheap mtl kit.
