I personally liked the toro atomics and just traded them for a set of toro hi lifts. The Atomics didnt seem to shred tall grass as well as some of the other mulchers out there like gator and such but on a regularly maintained lawn they performed very well for me and left a great cut. They lasted me about 25 hours new and about 20 hours on a resharpen. I still got them and will resharpen them again later. Nice blade IMO
