The fury edge is still a fine vaporizer - it's a middle of the road portable. The oven size is decent, good enough heatup times, and good battery life for that price point and size. I was pleased with the original HealthyRips Fury.

The HealthyRips Rogue is a newer device from HealthyRips which is a linear upgrade from the Fury Edge - slightly larger oven, slightly larger/stronger heater, and slightly larger battery. But same mouthpiece and flavor profile.

There are upgrades you can take from the Fury Edge, but if you're happy with what you got, I wouldn't stress about the need to upgrade unless there's something specifically you want (like better vapor flavor, larger oven, faster heatup, etc)
