I bought the Big Joe lll in January 2020. What intrigued me the most was the addition of the SloRoller. The technology of the SloRoller was to distribute smoke and heat in recirculating waves resulting in enhanced smoke flavor. This new technology works as advertised. I had a previous ceramic grill/smoker and didn't feel the smoke flavor was as good as on my offset stick smoker. That is no longer the case.
Also the new Big Joe lll requires very little assembly unlike many of the Kamado Joe competitors. Since purchasing the Big Joe Im haven't looked back and use it as may primary grill and smoker.
