I can't help you on the jump, I went from Blu to the Provari. I researched, thought about how long I'd be using it versus the cost of cigarettes and decided I'd go for it. I have not been disappointed. As others have done, I bought a second one. I've tried a progression of toppers; Protanks, atomizers, and carto tanks. When time and finances allow, I may try a rba. The Provari allows me to grow in my vaping experience at my own pace. Each step keeps getting better because I have a solid base to build on. I highly recommend it but you have to decide what's right for you.
