I picked up a N pro from a local smokers friendly last week. I wasn't too impressed at first but after a few days use and switching to using juice and refilling the carts, I am getting much better vapor and hit.
So far, two charged batteries last me all day and a full cart needs topping off/ priming 3 times but it keeps a nice constant flow.
I appreciate all the great info on the forums. Atleast I knew not to toss my used carts.
