This forge design is better than my previous ones. The burners' placement is close enough to each other to eliminate that \"cold\" spot in between them, making it that much more efficient. The refractory material would have been easier to install with rigidizer, which is not provided with this specific kit. However, it does the job just fine, and there is more than enough refractory material to line the forge. I recommend mixing no more than 2/3 of the bag for the initial coating, leaving you enough for later touch-ups. My main concern is the refractory brick length: one 9\" brick and one half (4.5\"), while the forge floor measures about 15.5\". Therefore, you are left with 2\" of lost floor space to support longer pieces. I wish Vevor would provide the full 9\" along with a 6.5\" second fire brick to close that gap. Otherwise, it is a well-designed, good-quality little forge with good burners. For the price point, you can't go wrong.
