My neighbour just had leaf filters installed (never mind the brand). He is pretty old and his daughter (who lives with him) insisted he get them because she doesn't like the idea of him cleaning out gutters.
The cost was fantastic. He could have paid to have his gutters cleaned a couple of times a year for decades and pocketed the difference.
We have a lot of pine needles in this neighbourhood. I have different and possibly not as good leaf filters on my house and have to clean them once in a while anyway - and I think he will too. I suggested he keep the installer's phone number handy so he can call him to come and clean his gutters from time to time.
