Sky is the color, and this is as simple as PAX gets. The Era Go takes every 0.5g and 1g PAX Era pod. There's nothing to set up: click in a pod and inhale. It heats to the right temperature every time, and an anti-clog feature works on its own to keep your pod flowing. The 300mAh battery can last up to 180 days on a charge, depending on use. It charges over USB-C in about 45 minutes. It's small, at just over 3 inches, so it slips into a coin pocket.
