It`s great!
I like it. It was a perfect fit for my 04 F150. On the down side I couldn`t find any pigtails for it here. But was way cheaper than letting Ford fix it!

Easy install
The dealer got me for over $250 last time a (1) sensor went out. I got wise this time around. I spent $50 bucks and got a set of 4. I replaced the one bad sensor (with the help of 1a video)in under two minutes and I now have three spares for the next time one goes out.

Videos are right on
Great product at a reasonable price. Delivered quickly. Followed the How To Videos, turned out to be easier than I thought it would be. The bonus being that I saved quite a few dollars as well.
Would highly recommend. GJF

Exact Fit, Excellent Price
Will always shop at 1A Auto. Local dealership wanted $200.00 each and even with shipping costs to Canada, still a great deal!

Wish I could buy individually
As I only needed 1 sensor I wish I could have purchased individually instead of packs of 4. Installed quickly and worked right away.

Sensors do not work. If something seems like a bargain - its not!
Installed 4 new sensors at a great price. Tested units with engine off. Only 1 sensor worked with a metal object (keys in hand). When backing up, sytems beeps rapidly. Changes to solid tone when you hit something (curb). Today sytem stopped working altogether - stays off. Waste of money - lesson learned! 2001 Ford F-350 Crew Cab Dually.

are these self contained then and the warning noise would be inside them and not in the van near the driver?
Karen M on Mar 8, 2016
BEST ANSWER: They make no noise on their own. These sensors are complete factory replacement units and plug into factory connections. They dont operate independently but rather send information to activate the factory in cab audible warning system as it was originally in your vehicle.
