        Awesome smoking rig!

        I purchased the 40" smoker and the slow smoker box for a serious rig! It all works great, the only thing I wish master built would do is put some dowel holders,at the top of the smoker so we can hang sausage. I made some dowel hangers for mine and it works very well!!

        overall a good smoker

        I received this as a retirement gift. I've never had a smoker before. I've done a beer chicken, several racks of ribs, and a port butt roast. The ribs were great using the 3-2-1 method. The smoker never quite reaches is maximum temperature of 275 degrees, about 260-265. For the chicken, even though the temperature probe in the thickest part of the breast said 165 the thighs were mildly undercooked. I wanted to make pulled pork of the pork roast but after 10-11 hours of cooking the roast only got to 165.

        Great smoker!

        I have had this smoker for 5 yrs. It has turned out the best food! One thing I finally figured out. This smoker creates a lot of steam. That is great for chicken, fish etc. that you want to retain the moisture. After smoking many briskets and not achieving the hard bark I liked due to the steam, I decided to try something. After loading chips in the side tray and got it to smoking I removed the slide in loader. I opened the top vent all the way. Wala, I finally achieved greatness. Removing the loader let the steam out and allowed my brisket to get a hard bark. Finally. Now I smoke my brisket 4 to 5 hrs and get the bark I want. Then I wrap and continue smoking until done. I really love this smoker!

        Great Smoker

        I have had this smoker for almost 2 months. I love how easy it is to use. So far I have smoked two whole chickens, a pork shoulder a tri tip steak and some jerky. It probably wont completely replace my large charcoal side box smoker but it allows me to smoke on weekdays when I normally would not have the time with my charcoal smoker. I also have had he slow smoke attachment which really compliments this smoker. I can do a 4-5 hour smoke and never touch it until its done.

        Another wonderful Masterbuilt product

        This is our second Masterbuilt smoker and we couldn't be happier with the purchase.
