I kinda did too but it is mostly replaceable battery devices because I know that my fixed battery devices will someday reach the end of their batteries lifetime. I have a pico and a clouper mini+ but only because I won them in contests. I won one subox mini kit in a contest (it was a pay it forward contest but the person I gave it to gave it back to me

) and have to admit that I just bought one because I like the kbox mini that comes in the kit. Don't know if I will ever use the topper that come with them though. I found the old school toppers that works for me and stopped the hunt once I found them. I have several rebuildable toppers but they will be a very last resort for me.
I am not saying that chasing the latest and greatest is a bad thing. In fact we wouldn't have all the choices we have today if not for those that kept working to get new, and in a lot of cases better, products out there for us and folks buying them and giving feedback as to what could be improved. gotta love all the folks that have made the vaping devices we have today and if left alone I can imagine how far we could go but if new products stopped being designed today I think there would still be something out there that would work and work well for everyone.
