Save your money. Every week you have to complain about grass in flower beds all over cars etc. I had them for three seasons and gave them every opportunity. My new service came and said it will take a couple of weeks to get my lawn back to normal. "Said the yard was a mess. Trying to get it all cleaned up. Said there was so many clipping left that they had to mow 3 times to get through everything. Said the Cherokee side of the yard was really thick with clippings and tall. He said they will never leave any large clumping or large clipping in yard." We'll see how the new service goes.
