Rated 1.0 out of 5.0 by Twisted into a knot I had this on one of my downspouts for two months before it twisted itself into a big knot. Totally not worth it. Just buy a expandable extender. June 11, 2013
Rated 1.0 out of 5.0 by Failed Some home owners have had a success with this product . . . I have not. It's been on my patio drain for about three months now and not once has it self-opened. As I write this there is an all day storm going on with a terrible down-pour at the moment, and that stupid extender is still rolled up. 'nuff said. January 18, 2015
Rated 1.0 out of 5.0 by Great for water but... Got clogged up with the first Spring rainfall & any debris (like the seeds that fall from Maple trees) plugs the holes. May 22, 2014
Rated 5.0 out of 5.0 by Works as designed I have no idea why it is not available in the store. I purchased that two months ago. Mounting was very very easy and it seems to work pretty fine. I wonder how it will survive freezing the water inside. Low price might suggest that it requires replacement after every winter. So far we already had here in NYC suburbs several times freezing weather and it still works fine. Pity that I took green one and in reality I needed it to be white and I saw elsewhere that there are white ones available too. December 10, 2013
Rated 4.0 out of 5.0 by Seems to work Ok Bought this to help a client with a rain water erosion issue, seems to be doing the trick, diffuses the water down to a drizzle. seems to stop the erosion. Sometimes is does not roll back up, but it does what I expected it to do.. I like it... August 19, 2014
