Verified Purchase
This fan came, the lid is creased. I thought no big deal I will use it anyway. looked inside the lid and there is no on board speed controller. Even though the description says that it comes with one OR you could purchase a wall mounted one. I spoke with two representatives who could not understand that and received an email for a link to the wall mounted speed switch as an answer. The wiring diagram is incorrect and the fan will not work hooked up direct.
