My BBQ is several years old and the existing lava rock was looking very tired. I searched the Internet for options and prices and noted great variation but I settled on the Campingaz Lava Rock as it was so cheap I'd could throw it away if it wasn't any good. I purchased 2 boxes, (6kg) as I have a large BBQ and it's actually great. Decent and consistent sized pieces of rock and not a bag of dust. Heats up nicely and dissipates heat well. Really, really competitive price.
Nice, even sized stone. Disperses the heat nice and evenly around my four burner gas BBQ. Adds that contemporary touch and allows the fat and oils to flare off giving the food that real and true smoky barbecue taste.
Have found that adding these has improved the food while reducing the amount of gas being used. because of their heat retention and dispersing qualities I find that I now need the burners on a lower setting that previously when no stone where employed.
Find everything cooks quickly and evenly.
One box maybe not enough to cover the plate of my particular grill but thought I would try one before committing to more.
Not a bad investment at under a fiver when purchased. A very good price compared to the exact same product from many other retailers. Arrived quicker that advised too.
Just enough lava rock in this bag for a small portable gas bbq but would need 3 or 4 bags for a standard bbq like most people use at home. It gave the taste of a traditional bbq but with the speed and more thorough cooking of gas.
The price and speed of delivery were very good but wish the bag of rocks was a little bigger.
