The Geras HeatGuard Pro is a pizza oven that needs a barbecue underneath it. You place the steel hood and ceramic stone on top of a gas, charcoal or wood grill, and the grill's burners or coals provide the heat. It is for people who already own a barbecue and want stone-baked pizza without buying, storing and fuelling a separate oven.

Our take
How a grill-top oven works
Geras describes the hood as designed to retain more heat around the pizza, while the stone spreads heat evenly and absorbs steam from the dough. The aim is a soft inside and a crisp crust. Because the heat source is your grill, the temperature you reach depends on how hot your barbecue runs.
The listing says no assembly is needed: set it on the grill and start cooking. It names Weber and Napoleon grills among those it works on.
In the box
You get the oven hood, a ceramic stone, an aluminium pizza peel and a recipe booklet. The specs mention a thermometer among its features, and the weight is given as 5.51 kg, with outer measurements of 43.2 x 40.6 x 14 cm.
The listing gives two sizes: the spec reads 15 Inch Pizza Oven, while the model name says Pizza Oven for Grill 12 Inch Pizza. Ask the seller which stone size you will receive, as it decides the pizzas you can make.
Storage and the guarantee
At 14 cm tall it stores flat on a shelf, which is a real advantage over a standalone oven with legs and a chimney. Geras offers a 6 month guarantee on its pizza kits, according to the listing, which is shorter than the cover offered with most standalone ovens.
Other routes to BBQ pizza
Kettle owners have two more focused options. The onlyfire kit replaces the lid gap with a ring, a 15 inch stone and a rotisserie, while the KettlePizza Basic 22.5 adds a front opening so the lid stays shut. The Geras is the only one of the three that is pitched at gas grills as well as charcoal.
Verdict
The Geras HeatGuard Pro is worth a look if you own a gas or charcoal grill and want the simplest way to try stone-baked pizza on it. If you have a 57 cm kettle, the onlyfire kit or KettlePizza Basic 22.5 are made for that shape. If you want reliable high heat without depending on your barbecue, a dedicated oven like the George Foreman dual fuel is the better route.
