Review on Pack of 4 Massca Downpipe Gutter Balloon Guards - Enhanced Filter Strainers for Optimal Performance by Joel Young

It was difficult to understand the actual size from the pictures. They do not work well in a regular gutter/downspout. I have two built in gutters that I bought them for and they fit in there. However, the part that goes into the drain pipe turned out to be surprisingly small. So I expect it to be blown away by the strong winds that hit Washington. I didn't replace any of the metal ones I already had, so I have 4 chances. Read other one star reviews.
