Rated 3.0 out of 5.0 by Mike Leaky but serves the purpose
I used this to run about 15' down a decent slope. No matter how I wiggled or pushed, there was significant leakage at every joint. It may or may not be an issue for your application. It was not a deal breaker for me. I needed the majority of the water to be redirected and it served that purpose. I did use some caulking to help curb the leaking. The connection to smaller sized downspots is awkward looking but again, serves the purpose.

The accordion part could be a little longer but overall this is a great buy for 10 bucks. I turn the blades off and drive the rider right over it when mowing, no more getting off and on again.

Rated 1.0 out of 5.0 by Zena a waste of money
This product did not connect well to my existing downspout and I needed more flexibility

Rated 5.0 out of 5.0 by Supertimm Great downspout extension
Thie Downspout extension is a very well built product and solves the problem of gushing water out of the downspout and gouging the landscaping. They install quickly and will rotate in any direction once fitted on the downspout. I wish they would have included a couple of screws to anchor the extension to the downspout. I also bought the downspout extensions which fit perfectly to the original Stealth-flow downspout and just clicks into place. The only thing I would add, is that there are no holes in the bottom of the extension or the original downspout extender. This, I think would add to mosquitoes breading in the ridges after a rain. I solved this problem by using a Dremal cutting tool to sliced slots in each of the ridges along the bottom so water would seep into the ground below. I also drilled a hole in each center support ridge so water would not collect there either. Both the downspout and the extensions are ruggedly built to withstand someone standing on them and should hold up well over time. Now I just need more wood chips to cover the extensions.

Rated 4.0 out of 5.0 by SafeT Works well to route water away from foundation.
After having foundation issues, was told by engineering firm that I needed to route all my gutter downspouts to discharge about 10 feet away from the foundation. The stealthflow was easy to attach to my existing downspouts and the extensions let you make the discharge as far away from the foundation as you like. These are not thick-walled plastic that will stand up to driving a vehicle across them. But they are fine for walking on or pushing a lawnmower across. They are about 2 inches tall. So I dug out a shallow trench so that the extensions are flush with the ground so that mowing over them is easy. I like these because they can stay in place and I can mow over them instead of having to move big plastic hoses around every time I mow.
