They are comfortable, waterproof, durable and fit in any car. The only thing to note is that they generate static electricity like nothing else. Now I'm in shock every time I get out of the car - it's never happened to me before. They also basically block thermal seats. If your car has heated seats I recommend using them in warmer weather as you won't feel the heat through these covers. All in all a fantastic product. Edit: Seat heating feels a little less, but definitely there. As for statics, it is enough to take the door at the exit only from the outside.
