I've been planning to have our gutters replaced for some time. They are not
in the greatest shape (lots of slope problems), and collect a lot of leaves
and pine needles because they only have screens protecting the gutters.

My plan has been to replace the existing units with some sort of solid
gutter cover...

So, I got estimates from 3 sources. One of 'em got ruled out completely
because the price was the highest of the 3 and the offer was "good right now
only". I don't care what you're selling, I smell a sham or a sucker deal
when the offer is "only good right now".

I realize that none of these systems is perfect, and some debris may get
into the gutters anyway. I also realize that some water may come over the
top of the system in hard rains, particularly in places where roof valleys
meet the gutters. Even with these problems, I think the top cover is a
better solution than me climbing a 25' ladder 3 or 4 times a year and
reaching into a filthy, wet gutter to remove debris.

Anyway, what experiences have people had with Gutter Guard, Leafguard,
Gutter Helmet, etc?

Thanks in advance..
