Great product. It clearly works as we've had installed now for a while and even during massive rain it works perfectly.
We also had it installed to keep sand out of our beach house gutters.
The professional who estimated the job was very prompt and professional and I was surprised by how much the installation crew did (cleaned all our gutters, rehung some that we not pitched correctly, reinforced and sealed all of them and the downspouts). I would definitely recommend.
