BUYING new microwave

Mine is a Russell Hobbs 800 watts . I bought it from Amazon .
I'm very happy with it .

Same as M0nica.
I think it's 850 watts, but does have a loud door,like early microwaves have, which I don't like.

Mine is 900 watts, a Samsung, with digital display which, as dalrymple23 says, is more accurate than the dial kind.
It’s not huge, and is brushed stainless steel. Came from curry’s if I remember correctly. It’s quite straightforward to use, unlike some models.

i have just bought the cheapest one I could find that matched my kitchen decor and fitted in the space provide What else matters?

In a previous life, have used many different ones in client's houses. Some are just too flipping complicated - unnecessarily so. My recent purchase was a Sharp 900w. Easy to use and has the power to cook things quickly. I also wanted one in white (not a great big black thing sitting on the worktop)! They are surprisingly few and far between. Digital are much easier to programme, rather than turning a knob, which can be iffy. Look at Amazon and read the reviews. Happy shopping!
