Been using for four months & find it's great as an "extra" oven.
The AUTO button is a godsend and adjusts the cooking time / temperature for you.
I have had great success with steaming fish (barrumundi), vegetables and we have now perfected dim sims! Oven beeps when food is cooked & automatically opens the oven door a crack to let out some steam... then another beep & safe to open.
Downside: due to the use of steam, the oven requires a big wipe down internally after use to get rid of excess water... not a big deal.
When using this steam oven you are only limited by your imagination.
Overall... I think it's an excellent oven (but you still need a normal oven).
