I want so bad to rate ATBBQ highly but I can’t. The delivery of the 1st YS 460s arrived damaged. It wasn’t on a pallet nor any protection. I realize it was FedEx freight that are at fault. My experience calling in was great. I actually spoke to the owner and then the Assistant Service Manager. They were both empathetic and apologetic for the bad experience. They turned around a replacement in 2 weeks and it delivered today. No damage. The problem is that the mat I ordered with the smoker didn’t come with the shipment. It was included when the damaged unit arrived but the driver suggested it would be better if I refused the entire shipment which is what I did. Then there’s the situation about the 1 vs. 2 piece diffuser. Yoder announced new units would include the 2 piece about 2 weeks after I ordered mine. I called but was told mine would still be shipped with the standard 1 piece. So I ordered the 2 piece diffuser. It arrived before the 1st damaged unit arrived. Well guess what, the replacement YS 640s that delivered today had the 2 piece. Now I have 2...I’m still going to hang in there with ATBBQ but I hope I have better luck in the future.
