Pros: Easy to use, not hot to touch

Cons: temp probes not accurate

NOTE this if for Masterbuilt 20070512 40-Inch Front Controller Electric Smoker I bought this through Amazon in the run up to Christmas.  Got a great deal on it.  It arrived in less than 48 hours and took less than an hour to assemble.


PROBE:  Has worked consistently for the month I have had it.  But, I am now realizing that it has worked consistently cooler than expected.  I have come to believe that both the cabinet probe and the meat probe are estimate the temp by 25F over.  Items have been taking longer than expected.  Meat is not as tender as expected.  I proceeded to use another meat probe thermometer and found out what was happening.  When the unit said my brisket was at 190 F, it was actually at 165 F.  Until I figured this out, I would sit and wait and wait and wait (Yes, I knew about the wall).  I would then kick up the temp of the unit and finish things off in desperation.  And it worked.  


Lesson learned -- confirm the accuracy of the unit.  Use alternative temp measuring devices.


But besides the temp monitoring the unit is great.  


Build:  Sturdy and solid. The unit is a bit low when it sits on the patio, i think I will build a platform (refuse to pay for one).  Really glad I got the 40" and not the 30"  I have put whole slabs of ribs on rack, no problem.  Whole brisket, no problem, whole salmon filet, no prob.


Cleaning:  I have had little issue cleaning.  Mostly I take all the parts out, remove large obvious stains/clumps/ grease and then put them in the dish washer on pots and pans.  Wiping down the other parts with soapy sponge works great.  Remember, it is a smoker, so I am not expecting spotless clean.


Remote control:  Remote works as advertised.  It is a replica of the control panel.  My only complaint and warning is that if you start it up at the smoker itself and then go pick up the remote and it on/off, you will turn the grill off and will need to reprogram cook temp and time.  I try to remember to not hit on/off but the light button which then seems to synch the two controllers.


Cooked so far: 2 briskets, 2 beef jerky, i pork butt, pork sausage (2), cheese, olives, salt, ribs (2), ham  


Overall : I love my new toy.  It produces much better product that I could ever do on my propane grill.  I only wish I had a bigger family to share all the goodness.


Pros: Stainless steal outer cabinet, internal temperature within 4 degrees of setting, probe within in 5 degrees. Doors does not leak.Top exhaust.

Cons: None so far

After FIVE, repeat Five Generation 2, 40" smokers, I finally have what appears to be a very reliable, accurate smoker. Masterbuilt replaced unit after unit of the poorly designed, poor quality 20070512 smokers that failed on so many levels. I was finally advised to forget the Gen 2 units and get Masterbuilt to send  the 20070311 model. Best move ever. This one has an all stainless steel cabinet. The controller is mounted in the top rear, maybe not as convenient as the front mount on Gen 2 but so what. This one has a light inside the cabinet. The exhaust vent is on the TOP where it should be. Very important, my AMNPS works in this one. No matter what I did or where I placed it in the Gen 2 it would not stay lit. Todd from A-Maze-n products which makes the AMNPS device, could not get one to work in his Gen 2 either. He also told me to go for the Gen 1 unit and that the Gen 2 is a piece of junk. I have made 2 pork shoulders and 3 St Louis ribs so far. I put the pork shoulder in at 10:00PM, filled the AMNPS, put temp @ 225 degrees and went to bed.The 9 pound shoulder was done by noon. the AMNPS smoked for almost 12 hours. The smoker did everything it was supposed to. Masterbuilt has one of the best customer service department I have ever dealt with. they will work with you and replace parts as needed. Maybe Masterbuilt will come out with a Generation 3 smoker, up the quality, and take the best from Gen 1 and Gen 2 and make a spectacular smoker.

Pros: Easy to start up, Takes normal chips, and does a good quality job with little effort

Cons: heat element wont keep up temperature in cold weather

 Overall I am very pleased with this smoker. It is very easy to use and smokes great food. The heating element does have problems keeping up in cold weather but gets the job done.


Pros: none so far

Cons: Doesnt Work

I bought this smoker on black Friday at Academy on sale for 199.99. I couldn't pass up such a deal. After starting up the prep phase, i set it at 275 for 3 hours like the book said. I walked inside the house came back out 10 minutes later and the LCD screen was off. I clicked a button on the control pad and it beeped and flashed 468. I called masterbuilt and they sent me a new control panel. 2 weeks later the panel finally came in and I started up the prep phase again. after 5 minutes the smoker shut of and would not come back on. I unplugged it and tried everything... NOTHING. I called masterbuilt and they told me to return it to Academy and exchange it for another. I got my new one last night and am planning on trying the prep phase on it this evening. Hopefully it will work and I can use the smoker.


Pros: Looks great

Cons: The digital controller has failed twice and I have been unable to smoke anything. Would not recommend this unit.

The digital controller has failed twice - once when I set it up, the other after they replaced it and I went to use it for the first time. Remote is a good idea but that didn't work either.


Pros: Very easy to set up and use, Wheels provide portability, comes with a remote to adjust temp and time.

Cons: Keeping smoke consistant and even can be difficult.

Overall, this is a great smoker! I have owned my MES 40 for a  few weeks now and I have very few complaints.


Out of the package it is very easy to set up and it comes with wheels so you can install it in your home and roll it out back. As soon as I could, I seasoned mine and then put it to use. The remote makes it even easier, however the range of the remote is about 10 feet. Perfect if your just standing around drinking beer. My only complaint about my smoker is the chip tray and loading system. Occasionally, some chips will not burn and it will stop smoking so I have to use something to put into the loading tray and even out the chips in the tray. It doesn't really effect anything, just requires more planning on my part as to when I need to add chips/ even the tray.


I highly recommend this smoker! It has worked like a charm for me everytime and I have enjoyed some very good Q!


Pros: Set and forget controls

Cons: Smoke at low temps terrible

I have had my MES for about 6 months now, and after adding a pellet burning tray I'm finally in love with it. I had problems getting decent smoke at lower temps but I've heard that's the most common problem with this unit. Using a pellet tray I've been turning out excellent cue. The controller on top is kind of flimsy but works fine, and I mostly rely on the remote anyway. Drip pan at the bottom with drain hole is a pain, if it's not lined up perfectly it clogs easily and drippings get all over the door sill. The light inside is almost useless, unless you're loading or unloading in the dark. Also, I've noticed that the meat probe can be inconsistent, so I expect a 5 degree margin of error and use a manual meat thermometer for accurate internal temps. Hope this feedback helps.


Pros: Easy to use.

Cons: none so far.

Got my Masterbuild electric Smoker  at noon and season it ASAP and later that night I made my first spare rib for the next day and BOY where they good!

The remote control is a most up here in the mountains of Maryland.... YES we have mountains in Maryland even if most Marylanders don't know that.

I love grilling and smoking. I'm the BBQ KING in this family trying to teach the grandkids the secrets but it is hard they have their iPods and Game stuff glued to their faced all the time, when they are not stuffing it with food.

The ease to use Masterbuild electric Smoker is that any novice can start using it as long as they can read a recipe and follow them. The internet is full of them and then we have the that helps a lot.

WE bought this at QVC and we (read me) Love it. But the others love to eat what comes out from it.

I too, love that I don't have to open to add chips and the remote control let me see the temp in the meat with the probe again without have to open and let out all the heat and smoke.

So here is the final thought to all that are "thinking" to buy one; EASY to use, Easy to use..... Oh did I say it's easy to use this electric smoker from Masterbuild. And everything that comes out from it is heavenly good. You will never forgive yourself that you have not got this one earlier. 

SO, let me tell you what you have to do....... GO AND GET IT TODAY!
