I purchased a brand new thermador pro grande range from factory builders. one of the coolong fans malfunctioned 3 days after arrival (10 days before Christmas). i called K&N that day to get warranty repair. scheduled me for the following monday but never called and never showed up. when i called them they said they cancelled my appointment! why? because factory builders never sent them proof of purchase. they never called and told me. scheduler is an absolute sociopath! what a lie!!! factory builders had documented all corresponence. they sent someone Christmas eve with the wrong parts and NO CLUE! still haven't heard from them. if you have warranty work, you're better of fixing it yourself.
Pros: none
Cons: fix it your self
