Industrial & Household Jewelry Casting Machine 1150℃ Oven Incubator Furnace With Visualization Window Burnout Equipment 1500W

Extremely poor quality. The door doesn't sit flush. The back wall inside cracked after 1 use. Claims 1150 C but doesn't even reach 1000 degrees. 960 is the maximum I'm seeing, and it's been an hour now. Came with this large and heavy steel plate with plasma/laser-cut logo, completely unnecessary, decorative, I'd rather not have it if it meant cheaper cost or better quality. First use - the unit steams like crazy and then leaks water. That means it wasn't completely dry nor was it tested. So no QA process. Coils and everything inside looks like it was put together/sculpted entirely by hand using ceramic blanket and refractory cement. It's crooked, sloppy. The coils are partially trapped inside the cement, which means it can't radiate the heat away and will not last too many firings. Radiant heat loss through the window is tremendous. anything sitting even half a meter away from the window - will catch on fire. Stickers on the door started charring at around 800 degrees

Nice oven. Unfortunately it doesn't come with instructions but it's easy enough to set the temperature.
