Masterbuilt® Slow and Cold Smoker Accessory Attachment With Removable Ash Tray for Masterbuilt Vertical BBQ Smokers in Black, 10" x 10" x 18", Model MB20100112

I purchased this Masterbuilt slow and cold smoker attachment back in 2018 and it’s still working great today, which says a lot about the build quality and reliability. Once you get it set up, it produces a steady, continuous smoke without constantly needing attention. The initial setup was a little challenging the first time — it takes some adjusting to get everything aligned and attached properly — but after that first install it’s been smooth sailing every time I use it. I’ve used it to smoke turkey legs, salmon, tri tip, and even for continental-style smoking to make jerky. The smoke flavor is consistent and really enhances the meat without overpowering it. It’s especially nice not having to constantly reload chips like with some other smoker setups. Pros: • Produces continuous, consistent smoke • Still works great after several years of use • Great for a variety of meats and jerky • Once installed, very easy to use Cons: • Initial setup can be a little tricky the first time Overall, this has been a great addition to my smoker and has held up extremely well over time. If you’re looking to expand into cold smoking or just want more consistent smoke without the hassle, this attachment is definitely worth it.

If you own an digital Masterbuilt smoker, you should buy this to get the full design capabilities of the smoker out of it. If you are thinking about buying one of these smokers, be aware that sooner rather than later you will be compelled to buy this. The current design of digital Masterbuilt smokers is designed to sell you a somewhat mobile, bare-bones unit at a reduced price with minimal electric consumption. Accordingly with these smokers, smoke is added to the food being smoked through an absolutely primitive arrangement -- you add a half-cup of wood chips to a thoroughly rinky-dink cutout in a tube assembly, slide it into the machine, and you get 45 minutes to an hour of smoke going through the smoker. After that time is up, you have to refill the chips. So, if you're smoking a full load in your smoker, you can expect to have to refill your smoker with wood chips 9 or 10 times over 6-7 hours. Masterbuilt advises you to bend down and look through the tube that the previously-mentioned tube assembly goes in to ascertain if the chips you put in before have burned down. Look into the orifice leaking smoke carefully. Because f you overfill the tray at the end of the tube, the tube assembly will jam. As dark and smoky as the orifice in the smoker that you're supposed to see clearly into, and given the low position it's in, not comparing it to a pig's nether hole is impossible. And every forty-five minutes, you're back shoving chips into the pighole, feeding the smoker. Oh, the people at Masterbuilt must have had a really good chuckle thinking this up. It's a hustle. You need this "cold smoking kit" to make the Masterbuilt electric smokers fully functional, a clear "gotcha fee" in addition to the original price of the smoker. This kit gives you a steady stream of smoke with the heating element burning the chips outside the smoker itself, so generating the smoke by using the kit minimally affects the temperature the smoker is kept at. The heating element inside the smoker itself is much more efficient and effective once the work of warming up the tray and making the chips smoke is taken off it, so the smoker stays closer to the target temperature. Finally, this device produces at least twice as much smoke for your smoker as the original tube-and-tray assembly, and that smoke flow is absolutely steady, instead of being governed by when the heating element in the smoker proper needs to turn on. The smoke is billed to last for six hours -- I've never managed to make the self-feeding chimney stack of chips do a full six hours, but it does drastically reduce the number of times you'll have to fill your newly modified smoker, and in addition to that refilling is much easier if you use a large funnel, makeshift or otherwise. This kit is not even sold as a "cold smoking kit" on the Masterbuilt retail packaging, it's a "slow smoker." The fact that it adds a cold-smoking capability to your electric smoker really is incidental to its design. After you bolt this kit on, you should use it for both hot and cold smoking. There are four other things you should know: 1. My Masterbuilt electric smoker has a set of wheels on it. Once you bolt this thing on, your smoker isn't moving anywhere safely. The assembly to attach the thing to the body of the smoker is clearly designed to be permanent 2. And once this is on, for a 30" smoker, you'll need the 40" Masterbuilt cover for it. 3. Remove the tube assembly and the chip tray that together formed the original wood chip delivery system when you attach this kit. It's not in the directions. 4. You'll need two power outlets to run your smoker with this kit attached. It only draws 1.25 amps.

After using the Masterbuilt 710 digital smoker, and reading reviews and advice from other users, I decided I needed this accessory to keep producing smoke while heating the main unit at a low temperature. I didn't read the fine print before I bought this; this unit was not meant for the 710 as it sits too low. So I had to create a shelf for it to sit upon so it could align with the smoke input hole on the 710. (See photos.) Now it works great, and I can smoke at temperatures such as 225 degrees (F) while still producing plenty of smoke. This unit just has an on-off switch. I consider it a must-have accessory for Masterbuilt smokers whether the recommended models or ones such as the 710 that need adapting. I can't guarantee it will work with other models, but with the 710 and a little work, it works great. It seems well-built and I've had no problems so far. It's worth the money. I would rate it a 5 if it adapted more easily to my Masterbuilt smoker.

Been putting off buying this for a while and I love it now that I got it works great can keep temps down and keep smoke on for a longer time

I really love this generator. Makes a lot of smoke. Easy to install and really not much setup. Can attach right to the smoker or use a 3" flex dryer vent tubing, depending on your needs. I attached mine too the side of my Masterbuilt smoker when I am doing a normal smoke such as pulled pork or brisket. When I cold smoke I use the 3" vent tubing so I don't add heat to the inside of my smoker. Have not had this smoke generator for very long so think for winter smoking may have to attach it to the side of the smoker for some heat. I am getting around 4 to 5 hours of smoke without having to add chips. Either way you set it up, cold smoke or hot smoke it's really easy to attach or vent tubing set up. Takes minutes. Would recommend this product to anyone who is into smoking food. Now what I don't like is every now and then the chips get stuck in the chimney. You have to push them down with a stick or anything that works for you. Problem is chimney needs to be a little wider because it's hard to find a even cut chip. It is the longer ones that get stuck and the smaller ones work great. As I said, if chimney was wider this would not be a problem. 2nd issue was the small screen on the bottom of the chimney is poorly welded together and falls apart really easy. I was only able to get 2 smokes out of mine before this happened. I contacted Masterbuilt and they sent me a new part without any issue at all. Was really surprised at how friendly and concerned they were with my issue. Didn't even ask me how long I had the generator for. With service like this I would be hard pressed to purchase from anyone else. Over all, I really love this Masterbuilt cold smoke generator. I am a paying customer and received nothing for this review, so it is unbiased 100%. I am giving this a 5 star only because of the customer service from Masterbuilt. Enjoy and keep the smoke rolling.

I think the idea of this unit is great, and I was able to use it twice, each time for a few hours. At the end of my second use, I noticed less smoke, but didn't bother to check the switch since it was daylight and it was hard to see if it was lit up. However, the next weekend, I was getting ready to have 20 people over and was getting ready to use it for smoked chicken when I noticed that the power switch would not light. I tried different outlets known to work. Still no power. I cleaned out the ash and wood and took a close look at it. It is a fairly simply device, so I suspect that something happened to the power switch, which would not light up. I kept it outside but under a cover when not in use and I never used it in the rain. I tried to call the company, but after being on hold for a long time, gave up and called Amazon. I explained that I had just bought it two weeks ago, had used it, and wondered if I could send it back used as a defective item. They said it was no problem. Thanks Amazon! So, they sent me a replacement. We'll see how it goes. Oh, and I did have all the black paint bubble up under the lid (see other reviews). This didn't bother me too much, but I was surprised, since I assumed that this happened after long smokes and/or long usage, not after two uses of about 3-4 h each. Finally, if you use the hook that comes with it to connect to a Masterbuilt digital electric smoker, the hook interferes with your sliding the smoker tray into the digital electric smoker. Basically, you can then only use this slow smoker to generate smoke. However, if you want to use charcoal or wood chunks (to get that smoke ring, see YouTube), you still need to use the smoke pan on the digital electric smoker. The chip feeder in the slow smoker is not big enough to accommodate a wood chunk, charcoal, and wood chips. One reviewer suggested using metal screws to fasten it, but I found that it still inserts and stays well enough connected without the hook. So my suggestions to the company are: 1) Use heat-resistant paint 2) Elminate the hook and come up with another way to fasten it. I don't know if the anyone else has had this power switch issue. So I hope that this is a one-off.

Cold smoker works great! Dry wood chips last about 2-3 hours, soaked wood chips last 4-6 hours. You can even use pellets in this thing, just dont fill it all the way because the pellets expand and will push the cap open (lasts 8 hours!) It's a gravity fed system, wood chips or pellets are placed inside a square tube with metal screen bottom, you fill it while unit is installed over the small electrical element. The metal cap for the tube keeps most of the smoke from escaping pushing it into your smoker. It has an ash catcher tray that you can remove to view the element and screen, it works better if you tap the metal tube or its cap occasionally to make the ashes drop allowing it to breathe and keep the smoke production high (ash blanket blocks air flow). Keep your main smokers exhaust vent slightly open to allow air to move through the unit to produce the most smoke, otherwise the smoke will escape through the lid or door instead, and smoke will be lost. The temperature stays cold, like it should. Just remember to keep the main smokers hearing element from turning on by not setting time or temperature, this way you're only using it to tell you what the temp is (when smoking cheese)... I keep the water pan full of ice, too. When using it for hot smoking, use the main unit to control temperature and time (obviously), just keep the side attachment unit (cold smoker) full of chips or pellets and do your thing. No more messing with the tiny chip tray! Make sure everything is assembled correctly before operating the unit (no stray washers or bolts in electrical connections or switch area. It's a simple system that needs minimal attention to keep it producing that perfect smoke. As far as design, it has a couple of issues, none of which affect the performance of the unit, just a little oversight that could be improved in the future. For example, the lower electrical vents on the unit dont allow it to sit flush against the main smoker (see pic), and the paint under the lid bubbles off (some sort of reaction from smoke and moisture with the paint). Also, you can't use the legs or it will not sit flush with the smoker at the bottom, this won't matter if you're using the stand for the main smoker. Attach it to the smoker using the hardware provided and omit the legs for the small smoke box, and plug the holes with something to ensure proper air flow restriction. You dont want too much air flow, nor do you want too little. You'll get the hang of it after a while. Small tweaks here and there, and it will be perfect.

Works great! It's the perfect upgrade to Masterbuilt electric smokers that allow you to add wood chips. I just don't understand why they don't build this into their smokers to begin with. I have the 40" digital with legs, and it's a no-brainer that this should have come with at purchase or been part of the design (smoking box on the side). Why should you have to add it? This device makes the Masterbuilt electric smoker superior to any other electric smoker. Once added, the smoker works easier and better, plus gives the additional benefit of cold smoking capability. I would have gladly paid for a model with the slow smoking box already attached. If you own a Masterbuilt electric, you need this.
