Bought quite a while ago and didn't want to check until I started using it. The value was very good. The product came with simple instructions and care instructions. I put it on my saw and haven't taken it off since the day it arrived. I didn't have to sharpen it or take it off the saw. I am very satisfied with this product. So I think he was on the saw for about 6 months. It ripped yesterday and today I'll see if I can weld it together.
