You've just reminded me that I bought one back in January and chucked it straight in the shed. Thanks! When the hot weather returns I'll give it a blast but I'm not expecting much luck as I only bought it due to the fact that my offer of £8 (they wanted 20) was accepted on Shpock. It's very yellowed plastic though so quite old.
This one you are selling looks fairly good nick. Well worth the money for any heat-haters like myself.
