ANYONE contact LEAF FILTER ?

...what’s their LINE ? .... they sure are doing a ton of advertising

Yes.
Tried to get an estimate in the Spring but no one showed.
Stepmom had a similar micromesh filter attached to her gutters.
She did it without anyone asking and almost paid 6K for it !
Tried to cancel but it was too late, but they knocked off 2K from the price as it was still within 24 hours of the written estimate, but the installer was already there.

Regardless, it won't stop you from having to clean your gutters.
You'll still have to clean the stuff that gets stuck to the screen.
It'll just be easier.
There are YOU TUBE videos of people reviewing it for the worse.
My 2 cents.

How about the attorneys who will represent you for cancer from talcum powder? WOOOO! BIG issue! Worthy of millions of emails every day!

I installed the ones from Costco On my shop and house a year ago and I couldn't be happier with the results. We get a lot of the "helicopters" off the maples and they keep them out as well as pine needles and leaves. And the install was a breeze.
