we do a similar one on web site including gas made by pyramid and hi-gear and never had a problem we did have a bad batch from sunncamp so refuse to stock now but they are all madfe in same factory hope this helps kevin
Mine is three years old works well. Very stable lasts about 3 hours per can of gas on full, I will recommend this model but there are cheap copies out there which had safety issues.
I love mine, and always take it with me. Great for taking that early morning chill off the tent, as well as sitting by in the evening. Recenty the office fire died on us (there is only me and my dad) so I dug mine out of the camping shed, and it really helped warm the office up. Must remember to retreive it from the office before the camping season starts.
