It is a Remoska unit available in the UK via Lakeland kitchens. Branches I know of are in Windermere and the Trafford Centre. There are two versions mine is the standard 400w version and there is a larger one. Can be used to roast or bake - Channa will probably have more knowledge of recipes. I did a trial meal of braising steak, potatoes and carrots + herbs using my 600 w inverter. Cooked for 90 minutes on my "leisure" battery without running the van engine. (My spare battery as yet is merely a heavy duty battery for a diesel van obtained from a scrapyard as previous to present upgrades it only needed to power led lights and charge phones). The cooker used to be guaranteed for life but recently is limited to three years. My older abused one failed but was returned to the Trafford Centre shop without receipt and was replaced without fuss. The only control is an on/off switch but I find it very useful.
