This is our summary and key points to consider based on customer reviews.


The Masterbuilt Smoker has generally favorable reviews but with a few performance and design issues. Customers generally like the electric functionality and the ease of assembly and use. However, some users were encountering difficulty with temperature control, with the smoker fluctuating outside the set ranges, and required modifications to work optimally. The size of the wood chip tray was also raised as an issue for some users.

Pros

  • 👍 Easy to assemble
  • 👌 Can accommodate a decent sized brisket (up to 10.5 lbs)

  • 😊 Quick to heat up
  • 🥳 Provides a decent smoke session

Cons

  • 👎 Some customers experienced sub-optimal temperature control
  • 😩 Wood chip tray needs frequent refills
  • 💔 Some customers were disappointed with the smoke production

  • 🔦 The digital display is dim and at an inconvenient angle

Should I Buy It?

Just keep in mind that some users reported needing to tweak the device for optimal functionality, and you might need constant refilling due to the smaller size of the wood chip tray.


  • Great Beginner Friendly Smoker
Size: 30-inch Digital with Window & Legs
I have had this right at a month now and have smoked on it four times (once a week). I have smoked bratwurst three times, chicken twice, and a Mac & Cheese once. Everytime my 14 yr old son would say it’s the best food he’s ever eaten… he eats anything and everything at 14 but he doesn’t normally compliment it so much so that’s saying something. I haven’t dug into the ribs or brisket yet, but will in the future. With the uses I have now I highly recommend this product, especially if you can get it under MSRP. The size is just right at 30” as I can smoke 16 large bratwurst and 8 chicken thighs at the same time. Could probably fit more, but I like to give the food room. It’s light enough I carry it by myself to and from the back years to use. The chicken only needed 90 minutes to hit 165 degree and the bratwurst only needed 50-60 minutes of burn time to hit 160 degree. I have been using hickory wood chips from Home Depot and they have been great. The smoker itself seems to be solid and of good quality. The material is metal and my magnetic Bluetooth thermometer sticks to it no problem. I set it at max 275 degree and the burn times have been great so far, but again I haven’t smoked a rib or brisket yet so I am sure they will take a lot longer. FYI this is my first smoker and second outside cooker period and it’s about as user friendly as possible if you take 5 minutes and read the instructions and the two pages of warnings lol. Oh it’s worth mentioning mine came with a small/medium dent in the corner. The packaging had no damage so it’s almost like they shipped a damaged one on purpose. I called and customer service gave me some options and I am happy with the outcome. 10/10 recommend! ... show more

  • Great Smoker For ANYONE
Size: 30-inch Digital with Window & Legs
Love this smoker! It is very easy to use and does an amazing job of smoking multiple types of meat. It is quite a deal for the price and built to last a long time.

  • Makes good food, but it's not perfect.
Size: 30-inch Digital with Window & Legs
Not too bad. Good temperature control but a small complaint, the heating element just doesn't really get hot enough for a deep smoke infusion. But even with a weak element, it technically does still infuse some smoke flavor. I'd almost say it's best to consider this a small oven with a smoke infusion rather than a full-on proper smoker. That said, I've found that with the cold smoke attachment rippin full time while you smoke, you can usually get great flavor. I've cooked a lot of good food in this, even did a brisket to great effect running it for about 16 hours (even though there wasn't a true bark, it was juicy and tender throughout). I think the thermometer on this isn't as good as it should be, so supplement with a food thermometer for better results. ... show more

  • Working great. Very few problems
Size: 30-inch Digital with Window & Legs
Got mine just in time for meat to get really expensive. But I'm making do with chicken and pork and rarely beef. Love it. I use it all the time. I was tired of burning everything in my charcoal grill. This is great for my diet. Basically I smoke a week's worth of lean meat and work it into my diet. Had my first smoked black-eyed peas and will be making them again. I also smoke unseasoned lean chicken meat for my dogs. Cheaper than dog snacks. I've lost a ton of weight and can't wait to do a ham or turkey. I've done two turkey breasts but am curious about smoked legs and wings. I don't like the odd way the drip pan has to be wedged in at the back. It feels almost like it's a part for a different unit. The overall design is good but I had a problem with the leg stabilizers. There are supposed to be two long and two short, but I got three long and one short. I had to work in the extra long one at an angle. I tried contacting for the part but found the number and website a bit frustrating. That strained, lopsided leg is the only thing that worries me about the unit. ... show more

  • I spoke too soon…
Size: 30-inch Digital with Window & Legs
Update: After using this smoker only twice I went to go use it again just now and the controls were fried. When I unscrewed the control panel from the smoker I noticed the fabric wrapping the wires was damp, so I opened it up to let it dry out, hoping that would help. Upon opening this cheaply made control panel I found all of the screws were rusted already and everything was smoky and greasy. The internal buttons were covered in the same smoky meat grease that was on the inside of the smoker and were not functioning. There is a hole from the top of the smoker to the control panel to let the power cable through, but it looks like smoke and steam from the smoker was getting into the panel and causing buildup and condensation. The smoker was stored under a covered porch with a cover, so it was not exposed to rain. This is really disappointing. We planned to use this smoker for Easter and now we have to change our whole menu plans because we can’t even turn it on. :( Can’t believe this was made with such poor quality and design. Original review: I’m super impressed with this smoker and would definitely suggest it to anyone trying to get into smoking. We started out making some chickens and steaks, which turned out very moist and delicious, so I then tried a whole brisket. It did great! The info about the smoker doesn’t say anything about brisket, but I tried it anyway and was not disappointed. It smoked it evenly and made a really nice bark. The automatic temp control and timer made it very easy to do while I was working from home. I put the brisket in in the morning and it was done by evening and all I had to do was top off the wood chips every once in a while and mop the meat with a sop. With smoked brisket being $30/lb at bbq joints this smoker has paid for itself already! I’m going to try smoking some homemade sausages in it soon. If you’re looking for an all purpose, economical smoker that will fit in even the smallest backyards, this is it! ... show more

I bought this as a gift for my husband and I am reaping the good food he produces. We use pellets and did get. Urned by to embers so pay attention to where they may land and take the proper precautions.

  • One damaged, one malfunctioning....little bit disappointed.
Size: 30-inch Digital with Window & Legs
I've owned 2 Masterbuilt smokers prior to this. They typically last 5-6 years, depending on how you store them and take care of them. I gave 3 stars because of the prior experiences. This time around the first one I received I returned because it arrived with a huge dent on the side/corner. I think in my return I mentioned the box was damages too. However as I packed it all for return, I realize the damage wasn't where the box was damages, but rather on a "protected" corner, suggesting it came from the factory with the big dent. Excited to get to smoking, I quickly opened up the replacement. Gave it a solid once over for damage. To my excitement, it was in good shape. Assembly went smoothly and I was ready to "break it in". When I plugged it in, I heard the beep that I always heard on my other smokers. Power! .....only not. The control module wouldn't come on at all. Also, if I shook the poser cord (this was learned by luck) it would beep again. I think it might have been bad wiring? But I wasn't sure and wasn't happy. Sent it back for a refund, rather than a replacement as I did with the damaged one. ... show more
