Very little assembly required. Getting the kettle in and out takes some getting used to, but then you are making great theatre-style popcorn, fast and easy! Tip #1: I melt the coconut oil in the microwave, add popcorn salt, and then pour it into the kettle. Much easier than trying to spoon it in. Yum, doesn't even need butter! Tip #2: I got a cheap red mechanic's cart at Harbor Freight.
