Mostly good ; minor fault.
The material that the mats are made of ; is quite good, especially for the price. However the ONLY nitpicking that I can do, concerns the eyelets that fit over the tabs on the floor. The opening of the grommets is noticeably larger than the tabs themselves, thereby my shoe tends to move the mat every time that I get in or out of my car. I'll figure something out to keep it from shifting. Maybe Velcro tabs or Upholstery pins. It's a minor annoyance that's not worth returning the mats for.
Quality seems good. But they still strongly smell of chemicals -- nylon/rubber after a couple of weeks. People asked if I had taken up smoking! I understand why the mats had to be have lots of "openings" for the seats in row 2 of my mini van to slide on the tracks, but I wish they didn't. I don't move the seats back and forth and I would have rather have had a solid mat to keep dirt out of the tracks. Now I worry that the tracks for the seats will get filled with gunk. Order arrived promptly.
