I have 2 solo's and a similar volcano type vape from the same company that makes the solo. The solo is good with 4 loaded tubes to get me through the night (pain wise) but the joints seem to kill the pain better for me. I still have yet to use the desk top model with whip and bags , tried it 2 xs and shelfed it.I think it's your lungs being used to smoke not vapor.
I coughed more at first and now don't unless I take a ridiculous hit......... Often.
Also don't get winded anymore and can breathe.
Not to mention way higher on a third the weed.
I converted bubba and Joes next..........when's it gonna be you?
I did not like it out in plain view, and I smoke in bed most times , several xs through the night.
