I never owned or tried the elevape sv, but I do have a few different on demand units. Does the 2.0 feel like it it worth it when there are other on demand convection units available? I really like that the unit is ready when you start taking a draw so it would be very discreet and quick to use on the go. I also like the design of it, but the coils are a bit confusing for me. Would I have to constantly tinker with them or would they be ready to use right out of the box? Does the unit need an initial burn off like other portables? How easy is the maintenance overall? Would you say this is an easy unit to share with others or is it better for solo sessions? And out of curiosity, for those that have one, what temperatures do you have your presets, set to?
