Solo is better in vapor production and taste, and requires very little cleaning. Pax is more stealthy and you have to clean it every 5-10 sessions. Solo is cheaper (about $130).
very nice.. ya im leaning towards the solo. besides the positive reviews ive been gettin about its vape potency and smoothness it just has such a clean sharp look to it [vapegreen]
