The range is beautiful, very heavy, and solid.  The grates are heavy duty. You can easily slide a heavy pot off of one burner to the next.  The stovetop burners light easily and are powerful.  The oven interior is a beautiful blue.  The oven racks glide out and in very smoothly.  But the problem is that the oven will not maintain a temperature.  Sometimes double the cooking time and still undercooked.  I am hoping that Kucht customer service can offer help to resolve this issue.  I have read in other reviews about a faulty thermostat?  I will update this review after I contact customer service.  I love this range.  If not for the oven not working properly, I would give it 5 stars.
