It took a long time to put this together - lots and lots of screws, nuts and so on with instructions as pictures without narrative. Variable heating height good, but cooking surface is small. The overall structure is not very rigid so moving it about is easiest if it is carried rather than rolled with the wheels, especially since there are no handles for pushing. Next time (if there ever is one) I'll buy something bigger and more substantial. I will have to buy a cover.
