    the plastic was stretched and was a little dirty from a garage
  

*by A***X on Reviewed in the United States on June 28, 2017*

Got this from amazon, It came in original box and wrapped in plastic, the plastic was stretched and was a little dirty from a garage.  I put some on my truck two months ago and they're without a doubt the best product I've installed. My f150 got these and I honestly wouldn't buy anything else. Please keep in mind I'm aware there's better products available at much higher prices but I'm not a race driver on a closed course, neither is half the folks who run them but that's their money, but for my money I refuse to buy cheap off name brand junk, and  draw the line at really high priced stuff that earned their reputation from spending money advertising rather than research, I usually go with mid priced stuff such as these and I found a real gem with these, I'd definitely recommend this to someone!
