If your roof is mostly long slopes down to the gutter with no valleys or other places where flow is concentrated, this stuff works great, as-is. If you have valleys or downspouts that come down from upper levels with a concentrated flow, it can cause isolated overflow problems that require a little customization. What I found from having it in place for two years is that "sheet flow" into the gutters, even during heavy downpours, is drained away exactly as advertised. Leaves and other debris will collect on it, but not to the point of clogging, and will indeed blow off when dry.

The problem occurs during really heavy rain where there is a valley or downspout from an upper area that concentrates runoff in one spot. In those situations, if there is debris, it can cause the heavier than typical flow to skim over the top. Keeping it clean in that area is all that's required to fix that. There's an additional problem when the point of concentration is too far upstream from the downspout. In my installation, there are two locations where the distance from concentrated flow to downspout is 20 feet or more. When the foam is clean, the concentrated flow will flow through the wedge of foam and into the gutter just fine, but the free area inside the gutter where the water can flow past the foam is too small and water backs up. An adventure up the ladder during a heavy rainstorm showed that at the high end near the point of concentration, my gutter was completely filled to the brim and pouring over like a waterfall, while 20 feet away near the downspout, the water was less than 1" deep.

My solution to open up more flow area, and so far it's working, is to cut the foam into an L shape using a utility knife. See the picture I've added. Don't cut the top part too thin or it will sag.

I had to repair/reattach my gutters...IN DECEMBER :-) So i decided to clean them out and get it done. Well i decided to see if i could get a gutter guard installed while doing this badly timed home repair. I found this Gutter Stuff Pro on Amazon and with Prime shipping speed I gave it a shot(without any research). It was the easiest home repair i have ever accomplished,and i have done MANY complicated ones while having little training(just winging it). After 3 months and 35 inches of snow, i can honestly say THE PRODUCT WORKS! No leaves or debris in either my gutters or downspouts,no mud/dirt either. It did not loosen or deteriorate in any way! I will update after the Summer,but right now I will smile as i keep my ladders in the shed without need of roof duty forever. Thanks Amazon!

Other reviewers have covered the main points but I can contribute to the conversation about how well a foam insert sheds leaves. We have a couple oak trees that drop copiously and continuously, so this was of interest to us.

We have found that installing this product as directed does in fact leave space for leaves to accumulate. I do think that our gutters are slightly deeper than most, but regardless, there is a flat shelf where leaves can build up.

I did a little experimenting, and found that another piece of foam placed upside down on top of the first piece leaves an angled surface. Leaves do seem to shed nicely off this sloped face. I have attached a photo that shows this nicely. You can see the middle space has the extra piece and it is clear. The foreground and background sections are starting to build up leaves. The only downside to this solution is that it costs twice as much per foot, but I was able to shop around and find it at a reasonable price.

For my installation, we used this and the "THERMWELL PRODUCTS VX620 6"x20' Plastic Gutt Guard" installed together. After over 2 years, the foam is still squishy and seems to have the same properties as the day I installed it. There are a couple places that an animal of some sort has chewed through the plastic gutter guard, but the GutterStuff is still working perfectly.

Clogged gutters can be a huge problem and cause all sorts of damage. So far, this has been the perfect solution to keep my gutter clear and free-flowing year round.

When I had my roof redone, the roofer frowned on my old guards that tucked up under the shingles. I bought a pack of these for an extreme problem area and the roofers highly recommended them. bought couple packs here and there over the summer and this fall just filled all my gutters. They seemed to perform well over the summer. The section I installed last year seemed to hold up well.

These are light weight and can be cut to length. They're also high-flow and you can't see them from the ground/road.

Not sure if the Pro stuff is worth the upgrade over regular. It appears to be better quality and should last longer, but time will tell.

The idea is genius in my opinion. I felt so good about the concept that I purchased 160 feet (>$400). The only problem is the product sits about an inch below the top of the gutter. I believe my gutters are standard size, and the product barely slips below the nails that hold the gutter to the house. But on top of the product small leaves, seed pods, and other stuff collects and stays there. Even with 40 mph winds we have had recently, the top of the product is covered with leaves, reducing the ability of rain to go into the gutter. And I know that in 6-12 months this will degrade and make cleaning gutters even more difficult than before.

Such a shame -- if they would just make the product bigger, or have a half-circle aluminum piece with many holes in it to let water thru, that sits underneath the product, which would raise the top of the product flush with the top of the gutter. I would not even care if 1/4 to 1/2 inch of the product showed from the street, as it would work beautifully then.

And maybe this is my fault, but I installed the entire 160 feet of product, so I don't believe I can return the product. Expensive mistake. Avoid this product.
