    Torn after less than a year.
    Bought a couple of these a year ago to get rain water farther away from the foundation. I've moved and adjusted one of them a few times to weed or string trim and that one has torn at three of the corrugations, so I feel like the plastic used is too thin. The second one is fine but if I move it, who knows. These should last longer than a year.

      I have several of these in my yard to direct the water coming out of my downspouts farther away from my house. The can be adjusted to run them under bushes so they are out of sight. The latest one I bought was to redirect the water from my downspout into a rain barrel I use to water my raised garden boxes

      Perfect replacement solution for our beat up downspouts elbows. Eliminated the splash blocks and gave us flexibility in odd spots to route the water flow.

      I needed to extend my gutter. * Its plastic flexible, extends diff lengths, bends. Works great. Has adapters available. * It could be cost effective to extend water to a water storage container.

      No UV resistance
      No UV resistance, they become brittle and break off. I bought two full sets for our house, each lasted about 18 months, worthless! A good idea but made of cheap plastic.

        Can trap mold
        I've had 6 of these White Flex-A-Spout Downspout Extensions on my house for about 8 years. Two of them on the southern side (which gets sun all day) broke apart, the others are still ok. I did notice when I changed out the old ones that there was mold on the inside, the accordion areas of the extension trap water and that's where the mold grows. I'm going to try some wet & forget sprayed on the inside to keep the mold from growing, that product is fantastic BTW. It reactivates every time it gets wet. I used a 1/2" weatherproof self tapping screw to attach the extender onto the downspout (see pic). I used to use metal extenders but my lawn guys always seem to hit them and bend them up, that's why I went this route with the plastic, they even held up thru about 4 hurricanes!

        Down in the spout
        I had to add this to the existing down spout to make the water stop eroding the flowerbed. It cut very easily to fit on both spouts, as pictured.
