Well mine is brilliant
It has two dials - defrost, low, med or high. Then how many minutes.
Simple. Like in the olden days. And cost about £30. It's only 700w but because it's small has a smaller area to cook, IYSWIM, so is powerful enough.
We've had fancypants ones with 93 different programmes & I never did work out what A3 or P3 meant etc. And the last one beeped five times when it had finished.
As you were!
