Being completely new to camping stoves I bought a Gaz 2 ring stove with grill. and paid for express shipping. This was fine but the gas bottles recommend for cooker are not compatible with the regulator they sent...it's very confusing and after paying for cooker plus 80euro for a camping Gaz bottle we arrived at site to find regulator not compatible with the bottle...so be careful as it seems the cooker works just as well on any bottle gas with the right regulator. Why print the recommended bottle on cooker box then supply a regulator that doesn't fit it without telling you??? Crazy. Then just to finish the whole sorry tale the regulator was broken. Seems like old stock they wanna ditch??? Because it was a Gaz cooker with Gaz bottled gas and a free Calor propane regulator? Faulty one to boot. Their response was you gotta read all the small print, except that's very annoying when it invalidates the big print . Why didn't they say free regulator doesn't fit the recommended Gaz bottle as stated on cooker? Big con.
