Hi, The last time I posted was a few years ago & I was "reprimanded" for not posting in the correct place....So I'll risk the toungue lashing & try again! I have been vaping with the joye ego c for years. I've been very satisfied with it but would like a change. What I like most about it is not having to mess with cartomizers..I like having only to change the atomizer head when needed. Also, I like the twist voltage feature of it. What would be worth investing in that would be similar to what I already have? Thanks!
