I brought 10 of these a month ago and put in top down pipes. Went out today and water is flowing over edge of new gutters. Leaves and silt gathers on top of guard and blocks drain. Look good but dont do the job. I would recommend not buying

I tried these recently to replace galvanised metal grates I had been using (they rust too quickly) and if used for their intended purpose, i.e. to prevent leaves, twigs, etc from clogging up the downpipe, they work perfectly. The only issue I had was that I had to cut sections out of two opposite sides so they would fit into the shape of my droppers. NOTE: You'll still need to clean your gutters regularly (Tip: Use a Stihl blower with a gutter cleaner attachment), otherwise these will get clogged and slow the speed at which the rainwater can drain away. But at least the leaves are much easier to clean out of the gutters than the downpipes, which is the whole idea with this product.
