I own an EVO and a VOLCANO and I am thinking of perhaps getting a PLENTY, I also own an AROMED and MIGHTY. I really love the evo but if I ever had to send it for repairs again I thought I might like something like the plenty that will not break on me. I wonder how the plenty compares to the volcano and mighty. I find the mighty is tolerable on many different temperatures but the volcano seems to be picky as in I need to keep the dial around 6 or so for it to be comfortable and still produce good vapor. Should I just buy another evo for a backup or is the plenty a nice experience in its own right and worth the 250$ I already own a mighty but I do feel like the mighty uses a bit more herb than the evo would, I also find that the volcano is similar in this department, maybe a bit moreso? How is the efficiency on the plenty vs the evo/mighty/volcano? Thanks FC!
