Repair service for Ooni Karu 12 pizza oven. If you Ooni has stopped cooking great pizza, not getting hot enough, then it’s likely the insulation inside has degraded or absorbed moisture. This service replaces the ceramic insulation and reseals the casing, ensuring you are back to cooking great pizza again. Simply post your Ooni to me, the service includes return postage, and will take approximately 10 days. THIS IS NOT THE SALE OF AN OONI OVEN, AT THIS PRICE THAT IS TOO GOOD TO BE TRUE, IF YOU'VE READ THIS FAR, PAUSE FOR A MOMENT, THEN SLOWLY RE-READ THE DESCRIPTION AGAIN.
