Best Smoker Ever

Best grill/smoker/griddle ever

I've had this smoker for 2 years now. I have one our churches father day smoked pork butt competition. Beating out much more expensive guys with offsets and pellet grills. Love that I can use a variety of fuel sources. It's amazing at coming to temp very quickly. The fact that I can smoke at 175 but also sear a steak at 700 degrees is just amazing. This is the best grill smoker combo on the market hands down.

Amazing Pizza Oven!

I got this pizza oven for my 800 series. The oven itself is very easy to place into the cooking chamber. The included side rails ensure that heat stays on the stone and doers not escape. The oven is very simply to use. Simply set temperature to 550 degrees and once heated slide your pizza in. In 3-4 minutes your pizza is perfectly cooked. There is no reason to turn or move the pizza. You cooks completely perfect without any effort. Clean up could not be more simple either. Simply turn the heat up in the cooking chamber and any leftover demos on the stone simply cooks off. Once cool you can just brush off the stone. This oven is well worth the price. The kids love making their own pizzas!

Easy to use and versatile

I have had my 1050 for a little over 3 years and it has worked fantastic the entire time. Keep it clean and the interior parts like the manifold won't rust out, and even if it does it is so easy to get replacement parts. It is large enough to even do whole turkeys with room to spare. It works great with a mix of charcoal and wood chunks, and can handle longer cooks with being checked every 2 - 3 hours just fine.

Masterbuilt 800 series

If you're looking for a charcoal-powered, tech-savvy, all-in-one outdoor cooker, the Masterbuilt Gravity Series 800+ delivers. It's ideal for backyard enthusiasts who want the flavor of lump charcoal with the ease of digital control. While it's not perfect, its versatility and performance justify the price tag.

Easy to light

I use the fire starters for my gravity series grill. They last a long time and are easy to light. I break off two pieces and never have a problem getting the charcoal to light enough to get the grill up to temp.

Great smoker

Bought this 4-5 years ago and I still use it. Works good, other than the digital temp controller is finicky in the cold weather

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.
