Excellent speedy service of my White Porcupine brush for the guttering of my conservatory. I use this particularly to stop the birds swimming in my gutter which then causes a mess on the windows. I was replacing some that I have used for 5 years. I recommend cutting into pieces. slightly larger than the distance between each bracket. This will make them easier to replace next time. (The first time, I had done it in a long length under several brackets and that was then more difficult to remove for replacement.) This porcupine gutter brush is one of those household items that I would not like to be without.
