Rated 4.3 out of 5 by 71 reviewers.
Rated 5.0 out of 5.0 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 5.0 out of 5.0 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 1.0 out of 5.0 by Hard to connect and it leaks...not worth the $s The intention of using this product is to move water to a location away from the downspout. While it looks neat, it simply doesn't work well at all. The extension pieces don't fully connect to the other pieces or to each other (they look like they perhaps could 'lock' together, but in reality they don't), so while it looks fine, it leaks heavily from each connection point, thus rendering it useless. I'm disappointed in this product, but didn't see any other viable options at HD. :( September 9, 2015
Rated 4.0 out of 5.0 by works Easy to attach. Wish there was some way to seal the opening around the downspout. Stands up to my walking over it all the time. Sadly did not stand up to the dog digging it up and running with it September 16, 2015
Rated 4.0 out of 5.0 by Low profile, easy to hide and works well Item was easy to install on existing downspouts after removing the elbow at the bottom. Best to do that to reduce any leaks. Had to cut off a few inches of the bottom of the downspout to get the proper angle so that the water was directed 'downhill' and to get it laying right. Extensions were also available and easy to use. So far very happy with this product. June 23, 2015

Rated 5.0 out of 5.0 by down spout drainage Like how this product spread drainage & turn n different directions. Good product n my opinion September 8, 2015
Rated 5.0 out of 5.0 by StealthFlow Downspout Extentions Easy to ensemble, took just a couple of minutes to put the two pieces together and attach to the gutters. September 1, 2015
