Rated 5 out of 5 by Downspout Extension These were the perfect product at a great price. A very simple way to get the water flow away from our foundation. Super-fast shipping too, HD ROCKS!!! December 17, 2014
Rated 5 out of 5 by Works great Works great and looks nice. Fit my 2x3 spouts with the included adapter (remove adapter for 3x4), just needed 2 smalls screws i had laying around to secure. Probably didn't need to screw them in, but I wanted to. Rain from each side of my roof end up at 2 downspouts so when it rains hard, there is a ton of water that was coming out of the normal 90 degree elbow & spout splash...some going back toward the house. Bought these and extensions and also dug down a foot or so and filled with stone so the water can drain properly. The product is high quality, but very light, so you need to cover with stone or mulch..or just have larger stones on either side like I have on one of mine temporarily. Check the pics. June 12, 2013
Rated 3 out of 5 by OK, but not great - I'd recommend this product, but only because it's a bit more convenient to install than its aluminum counterpart. I do like the low profile it offers, plus, the price at HD is better than many other sources. However, the item itself is a bit hyped. For example, I stepped on a single section one day and my whopping 165 lbs actually bent the poly. Granted, that's better what would happen when stepping on an aluminum downspout, but still, hardly SUV weight-bearing material as InvisaFlow's sales vid would have you believe. Finally, the system invariably has small leaks at virtually every seam - unless you have all the sections Perfectly sloped - which tends to be Very tricky. August 19, 2014
Rated 4 out of 5 by The Stealthy Stealthflow The low profile of the product makes it perfect for applications where there is foot traffic. I found it accidentally and wondered why it is only available online. It is the kind of thing that may well draw positive attention on the store shelf. July 22, 2014
Rated 5 out of 5 by Does What We Hoped It Would Do! Easy to assemble and install. Helps diffuse the water from the spout above our garage to the gutters at the edge of the garage roof. By diffusing the water...we don't have a big gush rushing down and OVER our the water flows down the shingles in a spread out way..into our gutter...and the black color matches our roofing shingles.
