Works as intended, easy to setup for my smoker firebox, have been used quite a bit and still like new, Fit good (all same exact size). Helped take up dead space in the oversized firebox, used less wood, and maintained a more constant temp throughout the cook.

After first order was cancelled by Amazon, this slightly more expensive product was ordered and received in a timely manner. Packaging was excellent and product received in flawless condition.

Works great so far

Delivered in excellent condition . No cracks or breaks.

Need a grate for a small fireplace..... Wallah :)

Bought a clay chiminea. Manufacturer recommended putting gravel and fire bricks at the base. The bricks are working great!

I used them to make a small knife forge. They work, but cracked on first gradual heating. It still works, but cannot be moved.

I made a mini forge using these 2 bricks, cut out a hollow inside and added a hole for the blowtorch, it kept the heat in enough to harden some 1095 steel so I am happy with the result.

Surprisingly large brick, they work
