We decided to wait till Christmas Day to try the regal steamer, as this would be the best test preparing dinner.
Normally a job full of saucepans  and kitchen full of steam.
To setup out of the box each tray was numbered so no issues setting up.
But very surprised we had six vegetables all in the steamer all on the same time in 30 min all the vegetables  were ready half the normal time, no cross over flavour and minimal cleaning. 
Very surprised by us all and took the stress out of Christmas dinner.
