Masterbuilt® Gravity Series® 800 Smoker Grill - Charcoal Grill plus Griddle Insert, Digital Control, App Connectivity, 800 Cooking Square Inches in Black, Model MB20040221

I've had my Masterbuilt 800 for 6 weeks now. 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.

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.

We so wanted this grill to be the crème de le crème of grills. 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.

I purchased the Masterbuilt Gravity Series 800 in December '24. I could not be more pleased with the performance of this amazing bbq smoker! Its construction is very solid overall (thick structural steel in legs, lid, outside of hopper and pans); however the charcoal burning section of the hopper (firebox) is relatively weak and not durable in the long run (thin stainless steel walls that will corrode in a few years of weekly or bi-weekly use). While this chamber has ceramic heat insulation panels behind the original firebox plates, this is insufficient for the very high temperature produced there. Fortunately, in the market there are modifications that make the Masterbuilt Gravity Series a true bbq war machine. As soon as I received the equipment, I bought some accessories from LSS mods (firebox, hopper cover, inlet grate for hopper, super-sear manifold with base and cover and ash bucket grate). I have posted some pictures of the "overhauling" process of this beautiful bbq smoker. Additionally, I have sealed the hopper gaskets with a high temperature sealant (Kraken), replaced the default thermometer with a beautiful Lavalock (3 in. Face, 3 in Stem, M8 Thread), purchased the Levain & Co Meat Temperature and Smoking Temperature Magnets, and modified the left service tray by making it hinged (for easy storage). Check out the video I uploaded! ;) With these modifications I'm sure I will extend the longevity of the smoker for many years to come! I can't wait to try the pizza oven accessory! I will keep you posted! :)

I purchased the Masterbuilt Gravity Series 800 and overall it looks like a very solid, well-designed product. However, mine arrived with cosmetic damage on the back, which is disappointing for a grill at this price point. Customer service was very attentive and responsive, and they provided a partial refund, which I appreciate. I haven’t fully tested it yet, but after assembling it, everything else seems in good condition and working as expected so far. I’ll be using it soon and will update this review once I’ve had a chance to fully test its performance. If it had arrived in perfect shape, this would easily be a 5-star product. Just make sure to check it carefully upon

Update: Finally got one that wasn't damaged and had it assembled, so far I've only used the griddle which definitely has hot-spot issues but they're easy enough to manage. Once lit, the grill does change temperature very quickly and maintains temperature well. I spent extra and bought the mod kit to strengthen the fire box and what not after reading other reviews of it wearing out quickly. I haven't had a chance to try the the wireless yet. While it's a lot easier than a normal charcoal grill, I'm not sure that I would spend the money again if I had to do it all over. Didn't get to use or even see it assembled. It was delivered, box looked mostly fine, but when the assembler removed everything and checked it all, the underside was damaged, and the side dented. Not light cosmetic damage, damaged as in the rivets busted and was unusable. Naturally it's out of stock as well so a replacement can't even be sent, I just have to keep watching for it to be in stock and hope the price is the same, as well as hope it won't be damaged as well. If I ever get one I can actually use, I might update my review.

This grill/griddle/smoker is absolutely incredible. It took me a while to put together, I didn’t want to ding it, strip screws etc. but by golly was it worth all that work! Since I put it together 4 days ago, I’ve grilled, griddled and smoked. The app is a perfect accompaniment as I get notifications when it’s preheated and ready to add food. There’s four prongs for meat thermometers which is awesome! As a woman working on building a brand, this thing is everything I hoped for and then way more. It’s costly yes, however, with so many functions it’s completely worth while. The temperature control of the 800 is unmatched to anything I’ve ever cooked on. The app and digital reader give you live temperature readings. I’ve always loved cooking on charcoal and this gives the charcoal flavor with the ease of a propane grill. I can’t wait to keep exploring with my new toy. Highly, highly recommend!

<update> WARNING -- Do NOT buy this grill if you ever hope to get parts for it or hope to interact with masterbuilt as a company at all. They are not reachable in any way that I can see. Not sure they'll care about this review either as I don't see them supporting their products at all. I needed to clean my grill and the gasket for the upper hopper lid had worn out, so I removed it assuming I could get a new one. I ordered directly from masterbuilt what I thought was the right thing, but it was the full upper-assembly for the hopper (without the lid) as there was no picture on their website -- how hard is it to have a picture for all the parts you sell? I reached out to their customer support for help and I've received literally zero communication back. There is no phone number, I only have a generic email, [email protected] (or something) and I've responded to the auto-confirmation email several times seeking help. I'm happy to purchase the right thing, but I have no idea what that is. I would also like to return the hopper assembly, but I see no way to do that, and they'll probably charge me the shipping to send it back. Very frustrated at this point as I have a $800 grill that I can't use and I see no way to get it back into a working state. I guess I could take a welding class and try and fix this problem myself? I've changed my review to 1-star because of this, and it's unfortunate because I really liked it, but it's just a huge hunk of useless metal sitting on my back porch now. </update> This grill is awesome, it maintains heat well, the hopper works wonderfully, I can hold temps for hrs at 225, or 350+. It heats up great and quickly too! However, EVERY TIME I start it up, I know I'm just going to hate life for at least 30 minutes and be ready to throw the entire thing out. They have this snazzy app that can be used to monitor the grill temp, and probes for connecting and monitoring temps on your phone. BUT, there is NO WAY to get it to connect. I'm about 25% success AT BEST. I have great wifi coverage, and bluetooth (staying close to the grill). I've tried removing and re-adding the grill to the app. It just sits and spins for several minutes. The light bulbs I paid $5 for work and connect more reliably than this thing. I'm a fairly experienced electrical engineer and I'm about 3 steps away from just ripping out all the guts of this stupid controller and just making my own. All the fan and temperature hardware is there, in a weekend, I can't imagine doing worse than they have done with this. It just frustrates me to no end that they've made such a great grill, but the user experience for the control is so so bad. It's 2023, this seriously should not be the hard part of this problem.

Very versatile

J'adore mon nouveau Masterbuilt je le recommande fortement

the smoker listed as a smoker grill assembly but the grill was missing-disapointing as it was expensive and no one returned my request to have the concern corrected
