First of all I love my YS640s. But more importantly I LOVE THIS COMPANY! Never have I ever experienced such AMAZINGLY AWESOME customer service from a company. I have had 2 minor issues with my smoker in the past 2 years and they have sent me the part needed before even addressing my issue. I even emailed once to find out what touch up paint they recommend because the bottle that came with my smoker wouldn't spray. They send me a brand new can of paint without even telling me. Even if I didn't like my smoker as much as I do, I would still buy their products just for the customer service and how much they care about their customers. Fortunately they care just as much about their fantastic products as well and deliver extremely well build products without cutting corners.
