We have always used Austrailian Heat Beads, however as I thought we were running low I bought a packet of Cobblestones which are very expensive compared to the Heat Beads. I used to get my AHB in Tesco, who haven't had any over the past couple of years. Used one last weekend and had no problem lighting it - although Richard had tried without success. As it was a packet of AHB turned up at the back of the camping shed. I went into B & Q earlier to see what camping goodies they had (a couple of tiny tents and a EHU - nothing I needed) and spotted they had Penn Heat Beads in.
We've tried Penn Heat beads and Australian heat beads, and we prefer cobblestones hands down, in fact I think we still have both sorts of heat beads buried in the garage! For me they can stay there lol
I'm in the Cobblestone camp, except when roasting joints where the heat beads are better.
CStones seem to go 'off' when you have had them for a while. I put a squirt of BBQ lighting Gel (£1.50) at Morrisons on mine and they light up a treat.
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.
