It Works
The look and feel is slightly different than the OEM unit (typical of Chinese copies) but it works OK and was very easy to install.

Good Replacement Part but not Original Part Quality
The part is great price wise, not having to pay $90 at the dealer. However it isn't the same as a Ford part; the switches are a lot stiffer, and the annoying part is that the interior night time lighting is dim at the directional arrows, yet light bleeds out around the switches between the switch and the armrest (and the part is secure in the armrest/notches). The part saves you money and functions just fine, but noticeably different.

The jury is still deliberating
In a few days I will be receiving my third power switch in the last year. The first one lasted a little less than a year. The second one lasted 2 weeks ( the drivers power window won't go down). However, this is just the product rating. 1A auto's customer service gets 5 stars. They are replacing the part with no questions asked. I was extremely impressed in the way in which they handle my problem.

Great Switch for the $$
Ordered the switch on Monday, received and installed by Wednesday! I used the 1A Auto video as a reference and it was installed within minutes! I would definitely buy this again if I needed too, but don't expect that happen anytime soon!
