Little late, but I picked up the arizer xq2 when I got a hernia and had to keep the coughing down.
I would definitely recommend getting one with a temperature control if you intend for medically over just getting high. With a temp control you can modify which cannabinoids you want. So a lower temp would provide for medical benefits, and a higher temperature is where the THC activates.
This is oversimplified, but there’s plenty of charts and resources out there about the temps and cannabinoids.
