I bought the Roller Nut Harvester to pick up acorns from a number of oak trees in my yard. Every year squirrels bury the acorns and annihilate my lawn. The harvester works in the sense that it picks up a ton of acorns. However, it also pulls up all the grass along the way. So, if you don't care about things around the acorns (like grass), then this product is probably for you. If you're like me and you want to save your lawn from acorns, then this is definitely NOT a solution. Raking the acorns is more effective.
