So I decided to try this set-up, received my gear today and all I can say is I love it! The carto doesn't seem to heat up almost at all (though the vape can get quite hot if you aren't careful), it is shorter than with the M201 atty that I have been using, and seems to be longer lasting than even the carts for the M201 (although I have mainly been dripping). It does take a few good puffs to get the atty primed and vaping smoothly, but once it is primed, the quantity of vape produced is fairly comparable to my M201 atty. I would highly recommend this set-up for anyone who doesn't want to have to carry a bottle of liquid around with them in addition to extra carts. The only thing I have yet to find out is how to refill the cartos, but hopefully that won't be much of a hassle.
