First, this is only my 2nd purchase with Wayfair and your customer service stunned me!  You were the only vendor that offered free shipping.  When the installer took the unit out of the box, the lower frame was damaged.  I boxed the unit back up expecting to have to return it but when I went online with Wayfair, they immediately shipped a new unit (received in 2 days!) and told me I could dispose of or donate the damaged item, which I did donate.  Customer service is extremely important to me and I was so impressed I will shop Wayfair again!
