Psycho, glad you're doing your homework before jumping in!

Wish I had done the same. I tried so many mods before getting my first Buzz.
I love my Provari, and pushing the button repeatedly isn't that big of a deal once you find your favorite settings -
BUT, I still use one of my Buzz's every day. It's my go-to mod, and travels with me everywhere I go.
I'm a little rough on my pv's and would never consider throwing my Provari in my purse and taking it out of the house.
I've dropped my Buzz on concrete (more than once), dropped it out the side of a Jeep, even got it stuck in a machine at work, and they've survived without a dent or a problem. Unfortunately it didn't survive a dunk in the dog's water bowl.

I can definitely say, Customer service at Notcigs is fantastic!!
Never had a problem with the threading at the top or bottom. Silky smooth even though I haven't used Noalox in ages. I get about 6-7 hours out of each set of batteries, and they're about six months old.
Whether you get the original or wait a little bit for the Pro, you'll be very happy.

I know I'm waiting with credit card in hand for the Pro line!
