Ok I've watched a ton of reviews on different regulated mods. I've read lots of articles geared towards beginners. I have decided an ego type isn't for me. So I have decided to go with a vv/vw mod. I want something that will last all day without recharging. I also want something I'm not going to have to replace often. Is an 18650 mod a better choice of me. How long does an internal battery mod last. Is it something I would hAve to replace every six months or a year given daily use. I realize that some of this is subjective ie how much you vape etc. But I haven't been able to locate any information on the lifespan of thrse devices. And I hate to say it but I kinda want a pretty device. I am looking at the pico the odyessy mini kit and the mvp 3.0 pro. The internal battery on the mvp is concerning me.
