From what I've seen and heard, Provaris are great and reliable, but for whatever reason, I see a lot of them pop up for sale. Before you decide, I would recommend watching GrimmGreens review, he goes over all the positives and negatives, which all I ever hear from most are the pros, no cons. You may want to look into a box mod too, if you're not opposed to the idea, you can get a good box mod for a decent price. Whatever you decide, happy vaping!
