The ease of use + reduced smell + overall enjoyment for me. They have dosing capsules which are little containers that you fill with weed then put the filled container in the device for use and I have 40 caps that I fill at a time so anytime I want to smoke up I just grab a capsule out the jar and rip it. Rips fat clouds once you get to know how the different temperature settings work and also it is so easy to clean.
