Bests & Worsts Reviews from Amazon

I was so shocked and even couldn't write this review. I bought a new Camry XLE in May 2016 and bought this cover seat to keep my car seat clean. After 4month later, I noticed that this cover ruined my light gray color seat leaving yellow stains. I cleaned in any ways but the stain didn't come off. Maybe little bit came off but please see the attached pictures. This product is only for dark color seats especially cloth seat, although it leaves stain, You don't notice. (there is a description but I didn't notice when purchasing, was it added recently?)
