great extenders for the price.

These extenders are exactly what I needed to help divert water from going under my house. They do not come with any kind of screws to attach them, they just slip right over the downspout. I love that I had an option on the color, I don't want white when it's laying on the grass, I'd rather have the darker green! It's very easy to install and extends a short distance. They do go inside each other to make even longer. I do recommend these but they seem flimsy. Maybe not messing with them, except when it's time fo cut grass, will extend the life of them.

Good for it's intended purpose

Gets the job done. Might be a good idea to store them indoors during the winter. Between the snow, ice, and cold , they don't always make it through until the following spring

Great extension to your rain gutter spout

These are very helpful. We have used these for years. You just push them onto the end spout of your rain gutter down spout and the rain won't puddle up. You can move it around to where you want the water directed.
