Ooni Karu 2. Save your money and get something else
We already have an older Ooni oven and decided to buy a new, better model for my wife as a present.
The Karu 2 was a lot more expensive than other brands, but I thought the new design would provide lots of advantages.
Having used it a few times, I would say that you are better off buying a cheaper oven.
It seems that Ooni are all about cool website pictures, descriptions and digital content, but offer little real advantages over cheap ovens.
There are no printed user instructions included in the box. I contacted Ooni and I was told that they do not provide them. Everything is online, so you will have your top of the range oven with some cheap home printed instructions. Same goes for hints, recipes, etc. All online and nothing printed. At least the oven itself is real and not app. or downloadable gimmick.
The Karu 2 is listed as multi-fuel. Once we received it, we tried unsuccessfully to use wood pellets. Searching thought their website I found, buried under an FAW, the fact that this model will not work with wood pellets or charcoal briquettes. So much for "multi fuel"!
The thermometer fitted to the new model does not provide an actual temperature value, but just a number of dashes in green, yellow or red. There is no information anywhere on the actual temperature that each dash represents. This seems completely useless, since all the recipes ask you to reach a certain temperature value. I contacted Ooni and, again, was told that this is how it is and there is no better information available. Apparently the thermometer is for a "rough indication" only and they advised me to buy yet another of their gizmos to measure the temperature accurately.
A friend has a far cheaper oven that makes pizza just as good as the Ooni. The only advantage I can see of my over is that it is slightly more sturdy and it comes with a far nicer cardboard box. His oven came with professionally printed user instructions, but does not have a really cool webpage full of lovely pictures and downloads.
