I wasn't entirely sure when I was looking for a combi oven if this was going to be the right one for me when I read reviews that the 900w microwave function was weak, but it's amazing! I had a previous 1000w microwave and I haven't noticed any difference in the way it heats. It's excellent. I love the auto defrosting function as well all the precook functions. I've yet to use it as a conventional oven but I have no doubt it will deliver. It's sleek and modern look fits perfectly in my kitchen and allowed me to free up much needed bench space by getting rid of my old microwave. Get one! You won't be disappointed.
