[EX Q]: I bought these on August 22nd and installed them right away. It's been a little over a month and around 5,000 miles and they are completely warped. Very disappointed with the overall quality of this product.
[EX A]: negative

[EX Q]: These pants are awesome. They protect your legs very well for welding. If you use your knees for low level welding, brick work, tiling, carpets or roofing, your knees will wear out before these pants do.
[EX A]: positive

[EX Q]: Adhesive completely gave out within 8 days of application, just fell off phone and won't adhere now. When it was on phone the glare off of this was horrible. Phone was almost unusable in car or outside because glare obscured phone. Would not have purchased if not for the "Amazon's Choice", feel like Amazon should refund everyone who purchased this especially since they have since removed the "Amazon Choice" designation. Horrible product give us our money back.
[EX A]:
negative
