First smoker I ever bought and I love it. The 18" is perfect size for the cooking I do. Very user friendly smoker and fun to use. Holds temperatures extremely well, don't have to babysit. Longest cook for me so far was a brisket that took just about 11 hours with fuel to spare. Definitely a set it and forget it smoker. I plan on cooking on this for many years to come, excellent product Weber, thank you!
