On first glance, the PAX 2 looks a lot like the original—which isn't a bad thing by any means. If it ain't broke, don't fix it. So the design team over at PAX (formerly Ploom) decided to eschew a complete overhaul, instead opting for small tweaks and intuitive enhancements on its flagship product.
Smaller and lighter than its predecessor, the PAX 2 features increased battery life, four heat settings (instead of five), a deeper oven, and a heat/motion sensing mouthpiece that ensures your lips and tongue never get burned while you indulge. And although I have yet to try the new "party-mode" (mostly due to lack of people to party with), I'm sure it's at least 10x as fun as your last visit to Chuck-E-Cheese.
