We had 2 ovens and a microwave when we put a new kitchen in. One of the ovens failed in the first year and had an element replaced under warranty. An element in the same oven has now failed.
The other oven and the microwave are fine.
They are bargain basement quality IMO. I dont think I’d use them again for appliances. I’d get hold of a copy of Which and use that to source them on the internet.
