Well made product. They fit my new steel 5” gutters very well. Pretty easy to install depending on flashing condition and eve height. Was able to tuck the back edge of guard underneath the roof flashing and didn’t need back screws. Some of my eves are 20’ above ground so the ladder work was a bit slower. Installer 230’ of gutter in approximately 6-8 hours. It hasn’t rained hard yet but I see no problem with my 12/4 pitch roof.
