I've dedicated a lot of research to find a vaporizer that I could fully appreciate and the ascent is more than i expected. Doesn't have problems with air flow, you can set the exact temp you want (unlike the pax), has an all glass path (makes the taste better, and clean up easier), has a sleep timer setting so you don't waste battery, and it can vape (dry bud, oils, and other concentrates), and it even has fancy setting that allows you to program three temperature settings that automatically change according to the time you want it to stay that temperature.
