I rarely leave a review, but I think I must this time.  
First of all, it was very clear to me that I received a box previously opened. Individual plastic packaging for blades was torn apart and bolts and nuts are out of the individual plastic bag which is closed (which would be impossible without opening the individual plastic bag). So I thought I should return this product and request a replacement.  
However, what's more horrible was Wayfair's customer service. I sent those photos and explained why it is opened product. The person I spoke with continue to argue that it is shipping damage and I will have to pay a shipping fee of $15 (for a $200 product) to return it! Why should I have to pay for the damage that was made by someone else who opened the box or FedEx who delivered it? I have enjoyed purchasing many products on Wayfair, but  would never another for the horrible customer service.
