I have had this for decades but haven't had a yard in decades so someone need this more than I do!
It was perfect for the spots that need a little more help with watering and the places where grubs have moved in. Just wet the lawn and step on the aerator to make holes in the turf to aid it getting nutrients and water to the roots.
I used it numerous times but no need for it nowadays.
Not interested in playing phone number games as I get enough spam calls as it is!
