I brought a PRIMO round in 2006 and recently noticed that the inner ceramic fire box had a circumferential crack. I estimate that I've used it >400 times. I've replaced the gaskets three times and the thermometer twice.

I decided that it was time to upgrade to an XL and while reviewing the PRIMO warranty, was reminded that the original ceramic parts were warranted for 20 years. I sent a picture to primo.warrantee.

PRIMO contacted me in under a week and for the price of shipping it is being replaced. Soon I'll have a new and good as new PRIMO. Excellent customer service. This is indeed a great product and US company.
