They were very friendly and did the work in a timely manner.
Pine needles still collect and icicles still form so system not as efficient as it should be. If Gutter Helmet does not have a cleaning/maintenance service, perhaps you should consider starting (or recommending) one; especially for us elderly folks with multiple story roofs (one with solar panels which probably also need routine cleaning), and a way to at least prevent the icicles from forming over exit doors. Please call 928 526-3625 to schedule an inspection. We are at 7000 feet elevation in Flagstaff.
They didn't work for us. We covered them up eventually and put in our own.
It was installed and there have been no problems at all.
It works fine; it looks like he just put it in, even though it's been a few years.
My husband commented that he appreciates not having to worry about pine needles in the gutters.
