To start with, they work amazing. I got stuck on the lake in deep snow. Put them on and drove out no problems. In fact, I drove for several miles and they were fine.
These things work great!!! I originally get these for my wife in case she gets stuck in the snow. They looked fast and easy to put on but I ended up getting stuck and it was a perfect test for these, they worked GREAT! Okay, they are not magical, but they do work great.
These appear to be very well made and heavy nice straps.
I have a large work truck and these worked great! No need to call for help, just strap them on and you'll be out of trouble in no time.
