Well I was super excited about this true sized mini but I have report my findings since having some more time. Everything works well and it is a great mini but, because of it's size, the carts do not last very long. Now, I am use to this with other minis but with the NEO, I am lucky to get 20 pulls before the taste is just YUCK (That is not the case with the mins I use) and they, for some reason, don't wish to play nice on refilling. Normally this would not bug me too much but at $14.00 for 5 (epuffer nano @ $8.95 for 5), yeah, umm, grr.
