Beautiful stove.  But the oven is louder than any appliance I've ever owned.  When I looked up other reviews on other sites, there are a lot of complaints about the fan noise - sounds like a motor inside that's not oiled.  For the original price and for a high end product like that Zline claims to be, I would expect the oven to be much much quieter.  Working with Wayfair right now to find a solution.  Will report back.
