Thanks for sharing, AngeLsLuv, and that really is a nice smiling cat avatar. Ninja cat, Cheshire, fierce hunter, lazy odalisque, cats have it all but especially they have that happy closed eye look that dogs, as great as they are too, can't hope to compete with. And nope, I'm not gonna say cats are M401's and dogs are 510's. I sometimes wonder if I would've stayed with vaping if my starting equipment weren't an M401 (the branded True Smoker Dragon). After nearly a year of vaping, I've pretty much tried all the major atomizers and the latest E2 cartomizer too but the M401 (and the M301/601) are unique for me, with the BE112 being the only non-Smoore that competes with the Smoores in tastiness. Oh yeah, I'll just throw this out there--the drip tip designed for the 306 will work on a 401 atty. The only caveat as with a 306 is the drip tip might be hard to get off without some force. I had to use a plier to get it off the 306. --OK, just tried getting it off the 401. Came off easy which is good.
