Works great, when it works

I use these with my AutoIgnite 545, but unfortunately they only light on the first try about half the time. I've found that blowing on the starter after about 30 seconds seems to work well, but that defeats the purpose of the "AutoIgnite" moniker.

Awesome smoker with a decent, not great, app

I've made many delicious meals on this smoker and it works great. I'm amazed at how easy it keeps my desired temp. I do think the app is a little lacking, unfortunately. If I want to change the temp through the app I often have to do it twice before it takes. And temperature updates don't update quite as often as I would prefer.

The Tactical Titan of Backyard BBQ 🔥

If Rambo retired and took up smoking meats, the Masterbuilt Gravity Series 1050 would be his weapon of choice. This beast doesn't just smoke, it strategically dominates flavor like it's leading a recon mission against bland brisket. 🛠️ Built Like a Barracks, Smokes Like a Dream • With 1050 square inches of cooking space, it's basically the aircraft carrier of smokers. You could feed a platoon—or just impress your in-laws. • The gravity-fed charcoal system is pure genius. Load it once, and it burns with the discipline of a drill sergeant: steady, reliable, and no-nonsense. • Digital controls? Check. WiFi and Bluetooth? Roger that. You can command this smoker from your phone like you're calling in an airstrike of hickory smoke. 🍖 Performance That Deserves a Salute • It hits 700°F like it's chasing down a target. Searing steaks? Done. Low-and-slow ribs? Roger. • Temperature recovery is faster than a motivated private after PT. Open the lid, close it, and boom—back in the zone. • The smoke flavor? Deep, rich, and layered like a well-planned ambush. It doesn't just cook—it infuses. 🧠 Jeremiah's Tactical Take As a veteran with 21½ years of service and a mind wired for diagnostics and precision, I can say this smoker passes every test. It's not just a backyard toy—it's a mission-ready flavor delivery system. The Masterbuilt 1050 respects your time, your charcoal, and your taste buds. And if it ever fails? You'll know exactly where to troubleshoot—because this rig was built with logic, not mystery. 🏅 Final Verdict The Masterbuilt 1050 isn't just a smoker. It's a strategic asset in your culinary arsenal. Whether you're feeding family or hosting a cookout worthy of a field promotion, this machine delivers results that'll make your neighbors salute your BBQ flag. 10/10. Would deploy again.

It's cheating

Everything about this grill is amazing, the charcoal gives it an amazing taste the fact that it's three products in one saves me so much space and the electric thermometer makes it so easy to repeat amazing results, it feels like cheating. I've had this product since 2020 and will never have another style grill/smoker/griddle.

Great smaller grill/smoker

This is an amazing grill /smoker for anyone that doesnt need a big cooking area. All of the taste and smoke from a stick burner, but has all the convenience of a pellet smoker. The only thing I would change is the ash catcher is very small and fills up quick. Masterbuilt should at least offer a larger ash collector.

Ease of a Pellet smoker, flavor of a charcoal smok

I had a pellet grill that I bought for the convenience of automatic feed. After a while I missed the flavor you get with a charcoal grill. So I thought I could get both with a gravity feed, but was concerned on the ability of it to feed charcoal without jamming or other problems. The unit was easy to put together and instructions were of sufficient detail. Then came the moment of truth. The first cook. Somewhat to my surprise it went well. I t was a 6 hour cook and had no problems. The charcoal was fed as needed and the desired temperature remained consistent throughout the cook. The rate of charcoal use was not excessive. I'll admit at first I was skeptical, but I have to admit that it gave me the ease and convenience of a pellet grill combined with the flavor of charcoal smoking. (and where I live, charcoal is cheaper than pellets.) "Exchanging" my pellet grill for this Gravity series was one of the better decisions I have made.

Its been a battle!

I was so excited to utilize the gravity fed smoker, but I have had constant struggles with the smoker and fan starting. Had to go through reddit conversations to find out how to remedy. Its still been a battle though. I've changed the fan, wires and sensors. The rotisserie also worked great the first time but would stop turning after. I contacted customer service and never heard back from them. Hope I just got a lemon and its not how the rest of their products are.

When will my item arrive?

Once shipped, items usually arrive within 3-5 business days. While UPS and FedEx are our carriers for smaller items, be aware that larger items and orders are shipped via freight. The freight process is a bit more complicated than what we've all come to expect for small parcels, so it's important that you're prepared and understand what's required of you well before delivery day.

  • Most freight products ship on a pallet
  • Some carriers will call to schedule a delivery window, while others will deliver the shipment to a reasonably accessible location closest to your residence (their goal is to deliver as near a garage door as they can).
  • We'll specify which process you can expect in your shipping confirmation email.

For carriers that schedule delivery appointments:

Carriers that schedule delivery appointments require you to be home for delivery and provide your signature. The delivery is made with a semi-truck with lift gate services, and the shipment is dropped off at the curb. If you authorize the shipping company to leave the delivery without a signature, BBQGuys can't be held responsible for damages that occur during delivery. As complicated as this process may seem, we've only scratched the surface here — please review our detailed guide to freight delivery so there are no surprises when a freight shipment heads your way.

For carriers that deliver without an appointment:

Carriers that deliver without an appointment don't require you to be home or set up a delivery window, and you aren't required to sign for the pallet(s). Instead of scheduling an appointment, arranging your schedule to be home for the delivery, and signing to confirm receipt, you can sit back and let your items come to you. If you're home at the time of the drop-off, you can request the driver place your delivery in the garage; if you're out of the house, the driver will leave it near the garage or doorstep.
