Superb for woks! I have an electric halogen hob which is brilliant. However, for a wok, with it's bowl shape, these little gas burners are perfect. They heat all the way underneath and up around the sides too. Great value + the portability factor on top of that..
aldi will start sell it for 7.99 very soon.
Cheesey where,s Caerphilly? :D
Do you have a link the cheapest I could find on ebay was £16.95 with gas £10.45 without
