I recently purchased a Hello 016 cartomizer kit from madvapes on sunday. I recieved it today which in my opinion is pretty good. I have been using this constantly for the past 3 hours and i have only found one thing that i don't like about it. The cartomizer does not screw all the way onto the battery, and this is with all of them that i have ( which are all from mv). Other than that it is great. The feel of it, the th, and the taste is all great. I will be doing a follow-up later in the week, but for my first impressions i give it a 9.5 out of 10.
