These gutter covers may be less effective than they say, but at least there are not leaves in here!
The truth is if you dont clean your gutters fairly often then they will be full like this if you live near tall trees or just have been through heavy weather.
I was hoping the phone would pick up the thickness of this sludge in the gutter but it felt like scooping out lasagne. Cleaning out this gutter was a good home improvement for sure!
