The gravity feed charcoal is a game changing design for me. You can layer the charcoal box with charcoal or charcoal wood, then wood pieces for smoking, then charcoal, etc. And the ash bucket is at the bottom and makes clean-up a snap. Assembly wasn't too bad. It may take you longer than you plan on so give yourself plenty of time. After assembly, be sure to season the grill correctly. Check out the videos on youtube for assistance. There is tons of information available. I know, because I think I watched them all. LOL I did make the most perfect smoked ribs I ever had. Along with grond beef jerkey, chicken, pork chops, wings, and fish. You can literally smoke something for a couple of hours, then turn up the grill to 700 degrees for finalizing cooking or searing if necessary. In about 7 minutes it will be up to temp from 250 degrees. No matter what temperature you set its pretty even and doesn't divate much at all. However be aware, like any other grills, there are your hot and cool spots inside. The griddle is a nice touch. The cooking manifold swtches out in about 30 seconds, and the griddle is HEAVY and a perfect surface to cook on and attaches easily. You shoud by some griddlle accessories for cooking on it however. I made smash burgers and they came out good and smelled up the neighborhood.. "cheezee bugar cheezee bugar, Pepsi, no Coke... I think it was the grilled onions. The control panel works well, but for some reason, somewhere between the time you turn it on and about 5 to 10 miutes later, the blower turns off and you have to repower the panel by turning it on and off. It works fine after that, but it has happenned 3 times already. Just be sure to monitor it at first until you get used to using it. I did download the app for operating the temp and timer from my phone. That worked well at first, but it is bluetooth, so if you walk away to far with your phone in your pocket you may loose connection and the fan will turn off. I generally don't use the app since I like to be outside with a beer and cigar when I'm queing. If your "on the fence" about buying one... don't be. You won't be sorry. I had a Trager pellet grill I bought 7 years ago. It was ok, but never really got the smoke taste I was missing like using the Masterbuilt. Plus, you cant sear with it, and it doesn't come with a GRIDDLE. Lastly, if you made it this far, search Masterbuilt mods. They're aftermarket accessories specifically for the grill. I bought the whole shebang before I put it together and am glad I did. If you have extra money do your research and get that also. Hope this helps. Happy grilling. Review: Works GREAT, but finicky electronics. Impressive customer service! - VERY happy with how this works once I get it up and running. It regulates temperature excellently and gives great-tasting meat. I am concerned, however, about the electronics. The blue-tooth / wifi worked until about half way through my first cooking (was slow-cooking a roast, so this was a several-hour affair), but then stopped working and I have not been able to get it to pair with either my iPhone of iPad since. Also, as I was starting my second cooking, the unit would not turn on. I checked all the connections, which seemed sound, but it still would not turn on. Finally, after I pressed the on button several times, it did come on and worked fine (except no blue tooth or wifi). Non-function of the remote capabilities is not a big deal: I'm pretty much always near the grill when using it anyway. However, I'm concerned about the control box in general: Is this finicky nature an indication that it may stop working soon? Again, that is my only concern. Otherwise, this is an amazing grill and I am very happy with it. 9/2/24 update: Continues to work, usually even with Wifi. It is still finnicky, but I can consistently get it to work. Masterbuilt actually contacted me with pointers, and then sent me a new control box. I have not installed it yet since I can always get the original one to work, but it is very nice to know I have it in case. EXCELLENT customer support, I would say. ## Features - Reaches 225 F in 8 minutes, 450 F in 10 minutes, or 700 degrees Fahrenheit in 14 minutes - Includes a flat top griddle insert and cast iron grill grates with 800 total square inches of cooking area (including the two porcelain-coated smoking racks) - DigitalFan minimizes heat fluctuations – maintains temperature - Control temperature and cook time with the digital control panel or with smart device control using WiFi or Bluetooth - Built-in temperature gauge and meat probe thermometer for perfect results every time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08XXDQTGZ | | Best Sellers Rank | #64,936 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #65 in Outdoor Smokers | | Brand | Masterbuilt | | Brand Name | Masterbuilt | | Color | Charcoal,Black | | Customer Reviews | 4.0 out of 5 stars 1,250 Reviews | | Fuel Type | Charcoal | | Included Components | Grill | | Inner Material | stainless_steel | | Item Dimensions D x W x H | 30.5"D x 55.1"W x 50.9"H | | Item Type Name | GS 800 | | Item Weight | 204.2 Pounds | | Manufacturer | Masterbuilt Manufacturing, LLC. | | Model Name | Gravity Series 800 | | Model Number | MB20040221 | | Outer Material | Iron | | Part Number | MB20040221 | | Power Source | Fuel Powered | | UPC | 094428276628 | | Warranty Description | 1 Year | ## Product Details - **Brand:** Masterbuilt - **Color:** Charcoal,Black - **Fuel Type:** Charcoal - **Item Weight:** 204.2 Pounds - **Manufacturer:** Masterbuilt Manufacturing, LLC. - **Model Name:** Gravity Series 800 - **Outer Material:** Iron - **Power Source:** Fuel Powered - **Product Dimensions:** 30.5"D x 55.1"W x 50.9"H - **UPC:** 094428276628 ## Images ![Masterbuilt® Gravity Series® 800 Smoker Grill - Charcoal Grill plus Griddle Insert, Digital Control, App Connectivity, 800 Cooking Square Inches in Black, Model MB20040221 - Image 1](https://m.media-amazon.com/images/I/71TYhCzhZ6L.jpg) ![Masterbuilt® Gravity Series® 800 Smoker Grill - Charcoal Grill plus Griddle Insert, Digital Control, App Connectivity, 800 Cooking Square Inches in Black, Model MB20040221 - Image 2](https://m.media-amazon.com/images/I/91rgN10uKzL.jpg) ![Masterbuilt® Gravity Series® 800 Smoker Grill - Charcoal Grill plus Griddle Insert, Digital Control, App Connectivity, 800 Cooking Square Inches in Black, Model MB20040221 - Image 3](https://m.media-amazon.com/images/I/71DnewxF80L.jpg) ![Masterbuilt® Gravity Series® 800 Smoker Grill - Charcoal Grill plus Griddle Insert, Digital Control, App Connectivity, 800 Cooking Square Inches in Black, Model MB20040221 - Image 4](https://m.media-amazon.com/images/I/81gjC1zOPDL.jpg) ![Masterbuilt® Gravity Series® 800 Smoker Grill - Charcoal Grill plus Griddle Insert, Digital Control, App Connectivity, 800 Cooking Square Inches in Black, Model MB20040221 - Image 5](https://m.media-amazon.com/images/I/71xzW8V3XKL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: If you have cooking at a 'lower' temp... Like 250 or something... Then crank it up to 700, how long does that take? Thanks** A: Mine literally takes a few minutes. I use it to reverse sear steaks all the time. I'll go low and slow (250) for 30 minutes or so and then crank it up to 650-700 to sear the meat. I remove the steaks in between but I can literally stand there and watch the temperature go up with the steaks in hand while it raises the temp. It's super fast. **Q: Is it possible to fit a 20 pound Turkey on this grill? Such as do the shelves get in the way or you can't close the lid?** A: The warming racks can be removed or adjusted. **Q: Does the grill produce a lot of smoke?** A: It does produce smoke - I use hardwood lump charcoal and some hickory chunks. This seems to produce more smoke than regular briquettes. It also improves the flavor of the food - imo. **Q: Does it work without power?** A: The unit will not function without power. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's a smoker, agrill, and comes with a GRIDDLE!! *by K***. on December 12, 2022* I've had my Masterbuilt 800 for 6 weeks now.

The ultimate grill for serious grill masters. This grill is the absolute perfect CONCEPT BUT WITH A FATAL FLAW DESIGN. We loved the fact that this grill could get up too 700 degrees and is gravity fed charcoal. You could cook a ton of stuff on it….if it worked properly. THE PROBLEM: It will only work as stated for the first 20 min- ie.,it will heat up, Fan will turn on until it gets to desired temp and then turn off until it drops 10-15 degrees, then back on to maintain that desired temp BUT FOR A SHORT PERIOD OF TIME of 20 min. AFTER THAT….the fan shuts off AND DOES NOT COME BACK ON until it reaches all the way down to 100 degrees F all the while you have your chicken or whatever else you are cooking is just sitting there on the grill barely warm. There are two side vents to help regulate the temp/fan as well, but even then, the fan stays off until it goes back to 100F. The temp sensor can connect to Bluetooth if you desire to troubleshoot. We’ve tried cooking on this grill several times even showing it off to friends and family because my husband was soooo excited about the ultimate design. We have tried cooking meat on this grill several times and it does the same thing over and over. We’ve had to always finish cooking out meat in the oven d/t it partially cooked because the grill fan continually shuts off after 15-20 min and does not turn back on until it gets all the way down to 100 degrees-clearly not enough heat to cook our meat. Forget it if you have a large party or want to smoke ribs or a pork butt. It will take hours and hours and nothing but a big fat embarassment. It’s like having a Tesla that loses its charge driving down the road…expensive, nice concept, but worthless if you want to eat dinner before 10pm. The irregular temp control makes thr meat unevenly cooked, under and over as you constantly have to troubleshoot the temp. We’ve watched countless YouTube videos, emailed customer service several times, and tried to contact a live person. They have very poor customer service, as it’s virtually impossible to get ahold of anyone except via email and they make you jump through multiple hoops by locating the serial number and taking a photo and sending in a receipt to prove you actually own the grill BEFORE YOU CAN EVEN SEND AN EMAIL TO GET HELP! The grill’s biggest defect is in the apparatus that controls the fan and temperature. We received quite lame email instructions back for trouble-shooting. Our first email back simply described how the fan and temp gauge worked, Duh! The third email stated how to reset the trmo sensor with WiFi or to make sure the proper codes were showing. I finally just emailed them to tell them we’d tried everything as my husband was willing to do everything within his power to get this grill to work properly. ONLY AFTER I SAID WE ARE RETURNING IT (as I was within a 2 day window of not being able to return back to Amazon)did the customer rep from masterbuilt call us as we’d left our number in the first email 2 weeks prior. He only said “well…I don’t know. Sorry”. That’s it. I’ve heard horror stories where others bought their grills on the Masterbuilt site and they put people off until the window is expired to return it. You must register this product with Masterbuilt in order to have parts covered under the one year warranty. This does not guarantee you can return it. Luckily, I returned it to Amazon within the allotted time frame for a full refund! Whew! I barely made it and would have been out almost $800 if not. Overall, this grill would be the bomb if the fan and temp sensor would regulate properly, otherwise you cannot use it like a regular grill since it’s gravity-fed. It’s rendered useless. Sadly, to my husbands disappointment, the customer service was so poor that we had no choice but to return it in time to get our money back. Hopefully one day someone can make it work. All other reviews on grills similar to this seem to have the epic fail between the fan and temp sensor-thereby, doesn’t work. ## Frequently Bought Together - Masterbuilt® Gravity Series® 800 Digital Charcoal Grill, Griddle and Smoker with Digital Control, App Connectivity and 800 Cooking Square Inches in Black, Model MB20040221 - Masterbuilt® Gravity Series 800 Digital Charcoal Grill and Smoker Durable Grill Cover with PVC Liner, Double-Stitching and Adjustable Drawstring in Black, Model MB20080221 - Masterbuilt® Pure-Parrafin All-Natural Odorless Wax Fire Starters for Charcoal Grilling, Made for Gravity Series but Compatible with All Charcoal Grills & Fireplaces, 48-Count, Model MB20091521 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/321995391-masterbuilt-gravity-series-800-smoker-grill-charcoal-grill-plus-griddle](https://www.desertcart.co.th/products/321995391-masterbuilt-gravity-series-800-smoker-grill-charcoal-grill-plus-griddle) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-05-13*
