It took me a little while to set up as the instructions were a little vague, in my opinion, but once set up and filled with water I added brocolli, corn on the cob and some diced swede in water using the special dish enclosed.  The appliance heated quick and the brocolli and sweetcorn was cooked to perfection.  Quite a bit of steam made but overall easy to use and once finished and cleaned stacked small for storage.
