I've never had a seatbelt that fit me correctly. It would scrap my neck, run away from the center of my chest. My Toyota has an adjuster on the inside of the mid section behind the seat. It raises up and down. So Toyota tried. I still never could get it to lay right. This folding, wallet type of adjuster is it! I've used plastic ones that clipped and were weakened by the heat of the sun, they'd crumble after a few months. I love this set of adjusters. Been using them now for weeks and they are comfortable and stay where you put them, when you click your seatbelt. Super easy to install, comfortable, no pinching or binding and it is neat as far as appearance goes. Not cheaply made either!!! I would recommend it to everyone I know.
