Iestyn,
Expensive but worth every penny!
Even though there's only 2 of us we have the "grand" the cooker certaintly does what it says on the can!
As for saving gas, YES it does, plus you're paying for electricity whether you use it or not, & the Remoska is such a misely user of electricity, you'd be hard pushed to trip the EHU using this.
Also it can be used to cook everything from a low fat "fry up brekkie to a full blown roast"!
Another plus is that its a doddle to clean the non stick pan!
