I've been using the skimmer for at least a decade On a hundred and fifty by a hundred foot pond and it finally wore Out so I needed a new one ! It works great but requires just a little bit of Practice To Throw, I have extended the rope for my large pond.And usually just pull it around the perimeter when the wind blows.
The debris to the shore , Great product I don't know how I'd maintain a clear pond without it !!!
