I have been testing the m201 against the kr808d-1 and i cannot tell you how much better the m201 is than a cartomizer.
I filled up a cart on the m201 this morning and after heavy vaping i only had to refill the cart once i would have gone through 3 or 4 cartomizers during the day with the heavy vaping i was doing.
The other nice thing besides the great throat hit and vapor is the m201 does not leak like the 801 does and the battery lasts for 4 or 5 hours i only had to switch batteries once.
Anyway if your not happy with a cartomizer and don't like to top off constantly give an m201 a try i think it's the best e-cig made so far and it costs less than most models.
