Review on 415 Wearwell by John Clark

It took about 15 days for it to fully unwind from the rolled up packaging and really start to work as it should. Now I feel very comfortable and my knees are very different from when I was standing and working in my workshop. I got this as a replacement for the same one that was 11 years old. It "wears really well". Excellent prices; excellent product. I was able to cut to the desired length and then bevel the edges myself with an orbital sander to remove some of the spongy material.
