Q & As

Rated 4.4 out of 5 by 63 reviewers.
Rated 5 out of 5 by Useful Cooker Bought this one to replace 27 year old panasonic that still works. Not as heavy as last one, so does seem a bit flimsy but cooks faster. Same size and so far been a dream to drive. very useful pre-sets. 20 February 2015
Rated 5 out of 5 by Great microwave I bought this as a replacement for an earlier model Panasonic and it is perfect! It does what I need and it is so very easy to use. 18 February 2015
Rated 5 out of 5 by No complaints We got this at a special price and wanted a 'no frills' microwave and it hasn't disappointed. Fingers crossed it lasts longer than our old flatbed microwave (5 years) 18 February 2015
Rated 5 out of 5 by Excellent Value - Ignore all the fancy instructions This was replacing one I'd had for 30 years. At first I was horrified by all the complicated instructions re defrosting etc. But in fact you can ignore all that.. Just two pushes of a button to get to defrost, then choose minutes in the usual way. Sturdier than I'd expected, and excellent that the fan goes on working until most of the moisture is dried out from the interior of the microwave. (But at first this was a bit startling - and you do have to listen for the quiet pings that say the selected time is up - or notice that the message now says 'Open the Door' even though the fan is still going). 18 February 2015
Rated 5 out of 5 by panasonic st452w microwave oven very pleased with this product, spacious inside, controls etc clearly marked, functions really well ,bought at a very good price 17 February 2015
Rated 4 out of 5 by works as expected Very powerful it cooks alot faster than our last microwave 17 February 2015
Rated 4 out of 5 by Useful Microwave Does what it says on the bit. Fan is rather noisy though. 17 February 2015
Rated 5 out of 5 by A Fine Microwave Oven This is an excellent piece of kitchen apparatus. I have yet to figure out/use many of the Chaos Defrost progs but on bread from the freezer is excellent. The Reheat progs are many too and soup arrives at perfect temperature. Only downside of this model seems to be that the clock disappears and has to be reset regularly if you actually NEED it to know the actual time of day ,confirming other reviews. But altogether a great piece of kit and if it lasts as long as the Panasonic it replaces, which is still operational after 15+ years, then it is worth every penny ! 17 February 2015
