Oh man, do not buy a Pax. Those are notorious for warm vape, and mediocre flavor. So many far superior vaporizers.
Arizer vapes are better than Pax. Arizer are solid vaporizers, very reliable and good quality vapor. Good price too. There are lots of really nice vaporizers on the market, but Arizer is a very good product, especially for the price. It's a good option for many people.
The Crafty and Mighty, S&B are two of the best vaporizers, and have been the industry standard for years. The Crafty is smaller and more portable, but also more prone to failure, and these are not the most reliable. The Mighty doesn't have as many reliability issues. The quality of the vapour from the S&B vapes is widely considered among the best. It's easy to use, no technique involved and gives you crazy clouds. These vapes are considered the industry gold standard. The vapour is cool and smooth. You cannot compare the quality of the Pax to a S&B vaporizer. In different leagues.
The Grasshopper is one of the most amazing vaporisers, amazing quality and with the coolest form factor.
They just released a revamped model literally this week, because the main issue with these are reliability, they used to break down very frequently, but they have a lifetime warranty, and now are more reliable with the new model. But the quality of the grasshopper, the stealth, and quality is amazing. One of the best vaporizers there is. Honestly, it absolutely destroys and shames the Pax. Reliability issues, but they do have a lifetime warranty.
There are also butane powered vaporizers, which are cheaper and can produce amazing results. Miaalana is an amazing one. Love that one. Only available in the states. Vapcaps, are really cheap and produce really great vapour. A vapcap is a good option for people.
German vape, Vapman, looks awesome, yet to try it. It's a portable/ home port fusion, very cool. Expensive though.
I'd recommend starting with one of the new Arizers or the Mighty. Easy to use, and great quality.
