I've got the Stoves mini range in jalapeño red, am very pleased with it, very well built and the finish is superb. When I looked at the whole range of Rangemasters I was a tad disappointed at the quality.
The place I went to said Rangemaster was better quality. I prefer the look of the induction Stoves as it doesn't have so many knobs. But my brother has a Stoves and the plastic knobs have broken after only about 3 years.
So I'm probably going with Rangemaster, even though I don't really like the shiny handles!
