Quality part
Was able to fix a 2016 Ford Fusion which had its brake lights on at all time even when the car was off, swapped this and the issue was gone. Very easy fix, and hasn't gone bad yet.

Easy replacment
Only had it in for a day and getting g rid of my truck limp mode is amazing, and probably the easiest repair/replacement I’ve ever done. Not even 5 min was needed

Awesome
Fixed my problem on my dad 2015 F250. Brake lights were staying on taking power from the engine, failed in middle of driving. Cruise would not set either when this happened, only turn light on in dash.

Direct fit
Direct fit esay installation well made working great... however ford needs to get their head out of their "ya know" and make the ground wire longer on the wiring harness .. what's the point of having a harness whip if the ground wire is 6 inches long? Anyway if I need one I'll buy again

Brake switch
This fit and was identical to the factory part. But when I installed it, I turned it, and it fell apart. I ended up purchasing the one from Ford, and there is a clear difference in quality. I'm sure this would have worked, but the plastic is definitely not as tough as the factory switch. Been in the automotive repair field for 26 years. Took a chance to save some money but I knew better.

Waste of money. The product failed to work
This was a very important part which I was sent a Chinese copy and which failed to work after installing it. The gear got stuck. Luckily, I was not very far from home. I had my family and children with me. Not sure, if I can claim a refund for a faulty part.
