Drain extension
Simple to use and install. Works well to reroute the water. I needed to reroute a drain from a certain spot and this extension was able to do the job. It’s bendable and easy to point it where you need it to go.

Perfect for my application
This bendable tube is only about 9 inches long. I wanted a flexible elbow to divert the end of a downspout a few inches at a right angle, so water would flow down the driveway instead of on the landscaping and grass. We used clear waterproof tape to secure it. With a right angle bend, I'd guess the pressure of a heavy rain would blow it off. Tape or a screw would be a wise move assuming you bought this for a bend.

Work great
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.

Exactly what was needed
My house was built 6 years ago and has since settled. The gutter drain spout separated from the buried downspout. When it rains it pours! Not down the downspout but sprays all around instead. The sump pump is right below this area. I’ve wanted to connect the two for a while now but haven’t found the part until now. THANK YOU for having this part! All I needed was a short length. This was perfect. It fit my gutter spout with a little aluminum bending and fit snugly into the PVC downspout. My part arrived in good condition, not misshapen or damaged at all. Took 5 minutes max to install… and only because I had to remove the gutter screws. 5 stars all the way!

Temporary Solution in the PNW
These get damaged easily. Plastic is thin. If you’re in a pinch, they’re perfect. Got them for $2 and couldn’t beat the price at the big box store. After about 2 months, we replaced with proper drainage. Size didn’t match spouts but worked for a temporary solution.

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.

Nice price!
They fit a little loose but will serve the purpose!

does the job
Nice design, expandable. Bright white. Short extension. Only problem is they are lightweight and can blow away in a storm. Hold up for several seasons.
