No, it's not! Having just purchased another Solo 2 because I found the S 3 so harsh at even low temperatures that I'm sending it down the road.. Huge clouds of vapor do you no good if they fry your lungs! The solo 2 does the job right and does it well. IMO very few vapes do their job better than the Solo 2! The now defunct DaVinci Ascent was a close second.
Sorry, I'm comparing the Solo Max ( S3 ) not the air Max. However, I feel both are over priced compared to the S2, but hey, spend ti if you've got it!
