Review: Worked for what I needed - Fits fine on a 3x4 downspout. A metal elbow wouldn't fit without digging up the ground so tried this flexible option. I attached to end of downspout and it now extends several inches onto the splash guard. Working as expected.
Review: Flexible - Flex drain is useful for extending a drain pipe when you need to have a curve for better water flow and standard metal curves don't work. The material is pretty sturdy and lasts for a few years.

### ⭐⭐⭐⭐ Work great
*by V***4 on February 12, 2026*

These Flex Drain Downspout Extensions work great. I gave 4 stars because they do come off the bottom of the gutter if it’s windy. I find myself playing hide and seek trying to find them the next morning. Other than that that, I do like how you can move them to an area where you want the water to flow out of the downspout. I haven’t had an issue with the cracking or breaking. I will purchase again if I need them in the future.
