Spotted this in local garden centre but held off buying it until I'd read some reviews. Ordered it anyway (not a lot of reviews on the web!) and it arrived quickly (ordered 30th, arrived 1st Nov) and set it up today on my gas BBQ. Followed instructions and first pizza took about 10-12 minutes to cook and not "in a matter of minutes" as stated on La Hacienda's webpage. Figured a lot of heat was escaping out the front so using a flat baking sheet closed off the front. This certainly helped in getting better results. Made three ~12" size thin crust pizzas and a peynirli in the end and after the initial pizza these turned out really quite good. So it does seem to do what it says on the box... I also suspect quite a lot of the heat from the gas burners is escaping up the sides of the Firebox - the Firebox sits snugly front and back with no gaps but there is about a two inch gap either side. I may try finding a way to close this off to ensure all the heat from the BBQ is actually directed into the Firebox.
Do not buy this. Despite using twice the amount of charcoal than would be required for a BBQ party, it did not retain the 'ideal 'heat. We put the first pizza in and the crust burnt black before the pizza itself was remotely cooked. In the end we gave up and put the pizzas in the oven. Big disappointment and £80 completely wasted.
Takes a bit of getting used to and there is an issue with the base over cooking, but this was the same in my friends pizza oven from B&Q, we had them side by side. First time I tried it I had it in ideal heat zone but it took 10 mins to cook, the second we put a small furnace underneath on the BBQ and the heat gauge went round and started again! Best pizza result I have ever had barring the base, but still tasted amazing. Going to try again after i have purchased a second stone to sit on top of the first, or might try the pizza on a tray then on the stone...... Anyway, it did as good as one of the BBQ pizza ovens people get With the heat under the stone the issue will always be there of overheating the base, a proper pizza over has the heat at the side This one will do me for now until I get a chance to build a pizza oven!
