Two trips with my Cadac 312-50 bargain and I'm well impressed.
Weekend mancamping (sleeping & breakfast in tent, everything else in pub) then two BBQs in idyllic Vale of Pewsey, and one 500gm cartridge is probably nearly empty. So not too bad on gas.
I intend buying an adaptor so that I can run it from an external gas tap on the caravan; that would be the cheapest gas.
The griddle plate cleaned up to like new each time. A great buy.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
