Any of the Arizer units are a good buy, IMO. I have owned the AirII and AirMax. The latter is my tool of choice now after the former did a hard dive onto a hard floor and broke the display. Contrary to the descriptions, these and the ArGo function as convection vapes if you load them properly. The other advantages I love are that you can load a bunch of stems and cap them, so when I sleep at night, I can have a fresh one ready to go if I need it. The other design thing I absolutely love is how easy these things are to keep clean. Stupid, dumb moron proof easy. Just pop the stems in 99%ISO for a couple hours, rinse with warm water, and let dry, and the things are literally good as new. No other vape that I have tried is so dead easy to effectively clean, and the stems last forever if you don't break them. In four years, I broke one, so not a big deal.
Anyway, good luck with vape shopping. IMO, don't bother looking for dual purpose, just get a nice vape for flower, and a separate one for rosin if you get a press.
