I like the idea and understand what they do, but wonder, bang for the buck are they that much of an asset. I can see shading the slides is a plus, also keeping the debris off is great and I heard it can keep the sun off the seal, but the noise? Of course I'm not as agile as I once was and climbing a ladder to clean them off although I might try a Dewalt air blower I have.
I just wonder if the money would be well spent somewhere else??
Thank you!
