This was my first ever set of chains bought for a planned trip to the mountains. Verify that you buy the right size. It can be confusing the first time you lay them out. I would say it's CRITICAL to try them out before you need them. Once you get familiar with the process it really is pretty genius. Putting them on without having to drive forward over them is quite easy. Make sure you open the ratchets and pull out the slack before you start . Supposedly they should be able to be removed without driving over, but I found that it's just easier to drive off of them once detached. Can't speak for long term durability as I may not use them again for quite a while.
