I bought this to replace a Panasonic MW that I have had for years. This is very similar and does the job. I didn't buy one that doubled up as an oven as I don't like the inconvenience of cleaning it. So far I've used it at least 40 times and only had to clean the turntable.
The power is good but it seems that although it can be set at 1000W my old one seemed more powerful at 800W hence 4*. And not 5*
Bought this in a hurry for Xmas, it arrived with time to spare & it's ease to use and large capacity are absolutely perfect. 2 family members are going to purchase this model to replace old, small & slower units.
