Yes, a device that uses interchangeable batteries would be my recommendation. I looked at the lavatube, and it is a nice mod. I searched for a review on it, and the only on I found compared it to the Provari. Didn't even know what a Provari was at that point, just comments here and there like "it's no Provari". Any who started reading the review on the lavatube, had every thing I was looking for, almost decided to buy it, then continued reading the review about the Provari, in every comparison the Provari beat out the lavatube, Build, performance, durability, warranty, function, reliability... the only thing the lavatube had was a smaller price tag. A starter kit for the lavatube, device, batteries, charger, atomizer, and a bottle of juice was $143, starter kit for the Provari was $209. but no juice, figured if I'm going to spending $150 for a device like the lavatube, I better search some more. After a week or so of searching reviewing and finding that most every other device was compared to a Provari, and the more I searched the more I wanted it. so am now a proud owner of a Provari.
Not saying that you should buy one, just saying to find a quality build that will last you years, find what you want, and buy it regardless the price. Better to be happy with what you get, it's an investment into your own well being and health. And what you aren't spending on smokes, will more than pay for your device in a few short month. Would I recommend a Provari, YES. The only people that wouldn't are those that never owned one used one or touched one.
Now begins the tough part, search and decision, then the wait for the arrival of your choice.
