I have only used it once. I hadn't cut tge grass in 5 weeks. The last 2 was just waiting for the parts once I ordered. I usually cut my parents and then my grass, every week. I have a smaller battery powered motor. So ofcourse it would be a little more challenging. So I will have a truer test the next time I cut. I do feel good about the new blade though.

The part worked wonderfully. A little slow in arriving, but very good bargain compared to what others were asking for the part.
