Hey, no doubt. I hardly ever buy one of anything if I even remotely think I'll need a backup. When I first started I bought a Blu kit and a Joye 510 kit. Didn't care much for the Blu but kept it for a backup for a week. Then bought another 510 kit, passthrough, and few other accessories: carts, attys, etc... Got a ProVape-1 last weekend and I really like it!! Collecting more and more flavored e-juice each week. Done with the tobacco flavor. Don't care much for it for about two weeks now.
