I've gone through several smokers and grills over the past fifteen years. I bought the Gravity Series 560 one year ago, and with the exception of the probe that died quickly, this is hands down the best smoking/grilling equipment I've ever used. I use it 3 to 5 times a week for everything from long brisket smokes to seared ribeye steaks. Are there better overall products out there? Presumably -- but it's going to cost you three or four times the price of the Gravity Series. I don't expect it to last forever given how much I use it -- but when it finally goes, the first grill/smoker I'll consider for replacing it will be a new Gravity Series.
