I've only used my Mighty, EVO and SV3 a handful of times since I got the Tubo. Initially, the mouth piece it came with got way too hot for my liking. I got a longer mouth piece and it solved that issue completely. Within a couple of weeks, the Tubo has risen up in rank and it's basically the first vape I go for now. Amazing flavour, super cool vapour with the right mouth piece and gets you extremely lifted! One thing... the screen above the coils... how the heck do I clean this?
