Peachy so far. Price was right, received quickly and matched the OEM measurements. Satisfied customer.

Very satisfied with this company. Ordered the part from another company and had nothing but problems. We found this place and the part was cheaper and they delivered the right part! Will do busy with again.

Ordered a Flex-a-lite 420 dual shrouded fan on Wednesday night and had it in my hands saturday afternoon! Great price and prompt shipping.

Overall quick shipping and nothing was missing or broken!<br>A little tricky install but fast with some help.<br>I like the fact that they have competitive pricing and there site is nice and secure.
