Easy install with one exception. The screws they provide are very short and metric. Thinking ahead (unusual for me), I purchased 1/4" white zip screws in a three-size kit. Given no house is perfect, I found the longer screws best for some areas while the smaller screws worked on the gutter guard fronts.

I finished approximately 40 feet on a porch and low roof within about 2-3 hours. I would purchase it again, but I will never need to :).

I purchased and installed this product in late summer 2014 after sitting through an exhausting presentation from one of those "leaf proof" systems that would have cost over $10,000 for roughly 200' of gutter. After the salesguy left and I stopped laughing, I went to Amazon and ordered this product and so far I'm delighted.

My house is in the northeast US and is surrounded by 70-80' trees. Falling leaves have been no problem and even those that took up temporary residence on top of the guard, blew off in a day or so and I have not had to do any "cleaning" of the gutter covers at all. We had several heavy rain storms and I found that the holes in the guards can handle a surprising amount of water, even in corner areas where you have a lot of water concentration from two roof surfaces. I had no issue with water gushing over the edge, and since the underlying gutter always remains clear of debris, the water flows smoothly to the downspouts and away from the house even in a prolonged downpour. As for the winter snow, I've had no issues with snow or ice piling up on top of the guards any more than would have occurred on an unguarded gutter, and since ice and snow can no longer accumulate INSIDE the gutter, the sunlight can melt the accumulated snow on top of the guard more quickly, and runoff from the melting snow and ice flows smoothly to the underlying gutter which always remains clear.

As far as the installation is concerned - you'll need to be comfortable being on top of a tall step ladder or extension ladder or find a friend who is. There is a lot of two handed work (e.g. holding the cover in one hand while you use the drill in your other hand) which you can't perform if one of your hands is white knuckled onto the ladder. I used a power drill for the screws, and you'll need a decent pair of tin snips to cut the guard to fit into any angled/cornered sections of the guttering. The cuts are simple and you can use the hole patterns in the cover system to insure your cuts are neat and straight. The product fit perfectly into the top of my guttering and was fairly easy to affix with the self tapping screws provided. The product sits just above the gutter mounting brackets so there is no need to make any "adjustments" to your gutter brackets - just drop in the covers and screw them in place. In a few places, my guttering had been "pinched" to be a bit narrower than normal or were "drooping" a bit wider than the standard 5" width, but it was pretty easy to spread the gutter out or push the sagging portion in before installing the screws. I would also note that for areas in the guttering that were sagging a bit, the cover actually helped provide additional support to the gutter, since the outer edge of the cover is affixed to the gutter and then the rear edge of the cover attaches directly to the house (fascia) which helps to pull up and straighten any sags in the guttering. I found it helpful to install the outer row of screws first for each section of cover, and then install the screws along the fascia board, then move to the next section of cover. Some of the rear edge screws are a bit of a challenge in areas where the gutter is installed high up under the last row of shingles, thus making it difficult to get your hand under the shingles to hold the screw while using your other hand to hold the drill. I'm guessing there is a gizmo at your local hardware store that would hold the screw directly on the end of your drill bit, so you might want to explore that to make it a bit easier. Once I worked out those installation details, it was pretty straightforward. It took me about a total of 10 hours over 2-3 days to install 200 feet of the product and much of that time was spent moving the extension ladder from one spot to another, and trimming and fitting pieces into the numerous corners in my guttering.

Nothing to dislike.

Unfortunately my stupid self ordered the 5" when I needed the 6". They accepted the return and sent out the 6". Very easy to work with.

This American made product is well designed, well executed, easy to install, and works great. I researched a bunch - used to have plastic guards, researched and rejected mesh ones because they fill up with mold. Looked at dozens that resebke this but lacked various features. The ribs on these create turbulence which makes the water go in the gutter. There are predrilled holes every foot front and back so they actually reinforce your gutter hangers and make things stronger. The back has a small foldover which doubles the metal and makes them stronger.

My degree is in engineering but I am also a guy who builds and works with his hands. I just cannot say enough good about this product. They even give a box of perfectly sized screws with extras for when you inevitably drop a few. If I could give these 10 stars I would. I wish every success to the manufacturer.
