Fast Delivery, Good Quality & a Good Price!
The package was slightly hit on the bottom of the box and resulted in 1 brick being broken. It is Not a problem however, I needed a few half bricks anyways. The bricks are very lightweight and should be just right for closing one end of my forge off. A few others are for resting a piece of metal on the outside of the forge entrance, for stability & support of the longer pieces of steel, with an adjustable height roller stand. I think that these bricks are perfect for their intended usage & price. They should last a few years minimum. With care, who knows how long. I would recommend these bricks to others. They are a good weight, size & the price is right also! A broken one is understandable & not a problem. Note: The second picture is the bottom of the box that shows where the foam insulation board was broken. It only broke 1 brick and it's almost in the middle of the brick. So it's not a problem! I Still Give'em 5 stars! 👍

Awesome Fire bricks!! Great product!!!
I have used these in a open fire lump charcoal outdoor grill for 6 months. They work great, easy to install they are in the bottom of the grill subjected to intense heat. No issues what so ever! I do have a coal/grate pan underneath the grill grates for the charcoal. Helps to clean ash and coal residue. They are a bit brittle if you are rough with then but mine are laid on a level surface. Dont pound on them as they will break!! No hammers allowed lol. Highly recommend.

Used these for a forge. Worked fine but real light.
When I got these they seemed real light for fire bricks. Wasn't sure if they would work for my forge. They seemed to work ok, but was expecting a more solid brick. They are very brittle also. All in all they worked but for the money could be better! Didn't seem to insulate as well as I hoped .

Work as advertised
These things weigh a ton! Nice quality bricks. We had quite a few that needed replacing and they right in. (Make sure you measure the size of your bricks.) We didn't have to cut any so I can't tell you about that, but they were easy to put in and fit like a charm.

Chipping as expected
Most blocks have some slight chipping

Pellet grill upgrade
I installed these in my old Traeger Texas Elite 34 pellet smoker. These have dramatically stabilized the temperature swings on my grill. I have used them in 20° temps with wind. I haven't noticed that it takes longer to heat the grill either. I use a smoke tube to get smoke, so it doesn't matter to me if the grill doesn't produce smoke through the auger cycling to compensate temps. It's a quality product that has many uses, including bbq year round.

They trim down!
These worked out great and I had to cut two down with my table saw to get the perfect fit in my stove. No issues with cutting if your wondering.

Good quality and price
Worked great in my 1992 wood stove. Packaging could be a little better as some of the bricks had damaged corners. Pro tip, look up the model of your wood stove and find the parts breakdown. It will show you the brick size and pattern so you know how to lay them and how many you need. This worked great with 1 or 2 bricks to spare.

Affordable replacements
Fit perfectly to replace my old worn fire bricks. Too soon to tell how they'll stand up to the heat but seem to work great as replacements.
