I just bought my second set of these covers. They are very durable. I used the first set for almost 10 years, often in the snow, salt, and road spray when pulling a snowmobile trailer, and they've held up well and remain fully functional. They are well worth the money to prevent corrosion and keep ice out of rachet straps. I also use them in the summer to keep a rachet strap from rubbing on my boat, and they work well in that application as well.
