Recently I decided that it was time to replace our microwave cooker with a new one and, having given it some thought decided to purchased a new NN-ST21QWBPQ from Panasonic Direct.
This decision was based upon nothing more than the enviable reputation Panasonic have built up over the years  for producing reliable and efficient products, and I have not been disappointed.
In my experience this is a great little microwave cooker because it fits in without taking up too much space, additionally and more importantly it does exactly what it says on the box and it is very quiet while it does it.
So, would I recommend it to any other prospective purchaser? 
Too right I would.
