I'm new to the whole seen, started vaping yesterday afternoon.
I read the reviews, and the tornado is my first PV, so can't compare it to much.
I was very impressed with the purchase from Totally Wicked, ordered it on Wednesday, I was vaping by Friday afternoon. The only downside currently, is one of the attys was dead (from what I can tell).
Charged a battery in about 2 hours, lasted me from 5pm till 3am, then a couple hours this morning.
Having heard about all the work that had to go into vaping with other models, this seems too easy. I screwed in the atty, screwed on the cone, popped in a cart and first hit was a huge surprise. Of course I didn't pay attention to the cart I used, and used a very low nic version, not good for coming off analogs.
I've been refilling the cart as I go with the KaMel liquid I ordered with my purchase, and couldn't be happier right now. It's taking a bit of getting used to, not going out for a cig, and a bit of a different flavor profile, but so far, it's getting me through the day.
Based on what I've ready about other PVs, this one seems almost too easy, and the purchase was too easy too.
