The newly redesigned Pax 3 has roughly the same form factor and features as the Pax 2, but with a more customizable experience to fine-tune your sessions and choose between loose leaf or concentrate materials. While you'll still find the built-in accelerometer and smart gesture controls, the heating system now warms up in a mere 15 seconds and offers double the heating power with three, easily swapped ovens: one full-size, one half-pack for shorter sessions and one attachment built for concentrates. A haptic feedback system also gives you a physical indicator so you can tell when you vapor is ready or the device has gone into standby mode.

Completely new is the "years in development" Pax Era, which borrows some looks from its nicotine-dispensing Juul cousins and claims to be the first temperature-controlled portable oil vaporizer. The Era foregoes the standard threaded cartridge system of other vape pens, but Pax claims its Era Pods offer a better flavor and more consistent vapor quality along with a more customizable experience. The Era also offers a few features that you won't find in other systems, like a "puff counter" on the LED display that helps you keep track of your sessions and integration with the new Pax Vapor app (more on that in a second). For now, however, you'll have to wait until the device goes on sale later this month to see if the proprietary pods catch on among retailers and concentrate producers. If Pax's distribution deals are any indicator, this hopefully won't be a problem.
