I think it is a great value and no slouch in performance either. I had one, sold it to a friend and bought myself an Air. I like the Air as well. If I were looking for a portable I would get a Solo or an Air. I kinda like the Solo a little bit better because it feels more solid and durable (not sure if it is), but I could not tell much if any any difference in performance. Main difference was using a shorter stem, which seems to change taste a little bit, better but hotter and the all my Air/Solo stems are interchangeable.
Both are winners. I like the air because it is a bit easier to fit into a pocket and the batteries are easily removed and charged. If I had a ton of money I would probably blow some on a Mighty just because I like vaporizers.
But I definitely don't NEED one.
The Solo is a great vaporizer especially for the price. The stems hold around .17-.24 grams or so and will sometimes last two 10 minute sessions for me (sometimes 3 but no flavor by then), but I can do a stem in a single session if I push it. I'm not sure what your tolerance is or if you already vape. But vaping .2 grams is almost like smoking .4 grams in my experience, once you get used to vapor only and work on technique.
That's what I would get if I had a budget of <$200 and was looking for a portable. EIther the Solo or the Air. The Solo fits good in the hand. The air I would get at least one extra battery for. I have 3 total. The solo already has two batteries built in. I liked the Solo so much I got an Air.
