Plenty of people have them because they are cheap. Yes they fade. But they look good for a season or two. It keeps your seats from getting stained.
As for durability, like I mentioned, a couple of years. If that fits your budget and needs, they work, and you can get a color that matches what you like.
If you want one purchase and never need to worry about your seats again, I recommend trek armor. Spendy but I will attest worth every penny. The material is strong, doesn't stain, has stitched in molle and pockets, comes with molle bags, and best of all made in the US. Stood up to trail riding, cross country move with 3 dogs, weekly trips to dog parks, fishing, camping, etc. Did I mention spendy?
I have them from the Previous Owner in the all black flavor. Just over all a cheap product that looks good new and helps to cover up worn or ugly stock interiors.
Pros--- Cheap and they do look good when new. Easy to remove and machine wash.
Cons--- Cheap mass produced Chinese product. They do fade. They are hot and the hardware is crap. Most of the buckles on my set are broken.
Trek Armors will be here on Friday!

Coverking seat covers are not good. I've had mine for 2 years and have wanted to replace them for a while. They stain very easy ( dang birds took a crap on my passenger seat when the top was off) and if you try to wash them they come out very faded and dull. Not good quality, not waterproof or resistant. Rip and tear very easily. I thought neoprene seat covers would be as durable and waterproof as my duck hunting waders, but I couldn't have been more wrong. Ill never buy another neoprene set ever again.
