I use a few different gutter covers, but none have work as well as these. The problem is...if the holes are too large stuff(pine needles, small leaves, etc.) will get through. If the holes are too small the gutter guard will clog quickly. I have a ranch house(flat roof) with lots of tree around it. I installed these gutter covers a little over 2 years ago. And I have not cleaned them off since installing them. Normally I would have to clean the gutter out 2-3 times a year. And even then I would get overflowing gutters. My gutters never overflowed with these covers. As you could see from the before and after pictures my gutters were close to being clogged, but never did completely. FYI - I use a leave blower to clean the gutter covers.

Came a little bent, but otherwise good condition. Fit perfectly on my 6 inch gutters, snapped right in. Popes some screws in and it's solid. I installed 100' in about 90 mins Cheapest quote was 400$ for practically the same product. Very happy so far. We'll see if it causes any issues will spill over when the next downpour hits, but I'm optimistic. At least it won't be full of leaves.

The product is highly recommended. But be aware that there are different sized gutters - 4", 5" and 6". Next do not get a flimsy gutter guard. Also, it is safer to use a ladder for installation rather than to lean over the roof. Most gutter guards do not come with screws. But self tapping screws # 8X1/2" are readily available and are inexpensive. 100 screws are about $10-12. Installation is not at all difficult. Still, as well as the product works, I would still make a yearly visual check from a ladder once a year. Remove a single gutter guard near a leader and send a stream of water through the gutter to clear any debris that may have slipped through the tiny holes, e.g. pine needles - as the product is almost, but not quite perfect.

Installed about 45' today with an inside corner. Took about an hour. Tin snips worked well to angle cut for the inside corner. The holes are also at a 45* angle, providing a great cutting guide. The overlap notches are super helpful, too. For our application, it was installed behind the drip edge for a great fit (the included instructions showed the install to the front of the drip edge, but in our case, that wouldn't have worked). The only suggestion would be to include screws - 1/2 self-tapping worked perfectly.

I got a quote on a gutter install and decided I would skip the install of a gutter guard and install a Gutter brush myself. (Of course, I'm sure I'm in the majority who gets an upsell to do the roof after the salesman checks things out.) I researched a little and I came a cross these Amazon Recommended A-M Gutter Guards, which were $100 cheaper than the Gutter Brush, and, more importantly, were designed to eliminate the need for annual cleaning for most people. I knew it was going to be a little more work having to screw them in, but the long term rewards would make it worth it. I really don't like going up on a ladder, and my yard is uneven making it all that more difficult. Plus, I'm getting up there in age at 67, so I want to go up there as little as possible.

My original plan was to install these while on the roof, but it was really hard to see what was going on in that position. The first section I tried would not go in place. So, I moved the ladder under the gutter, and the problem was that the roofers forgot to screw in one of the gutter mounts. I could not see that from above. So, at that point, I decided to do the whole job from the ladder.

Everything, for the most part, went well. I went left to right, front of the house to the back. The final few feet of my gutter were a little tight for some reason, so I had to cut down the width of the gutter guard to get it to fit in place. The aluminum is easy to work with and I was able to cut it to size with tin snips. It was getting a little hot out and I was pretty exhausted, so I'm thinking I might give it another go at another time. I have plenty of spare panels that I can work with, AAMOF, I think they give you a few extra panels, which is nice.

I ordered these on Saturday, the day after my roof and gutters were installed, and Amazon delivered them to me on Sunday, with the screws I ordered, when both of these items were expected to be delivered the next Friday. Very nice of them! Since I do not have prime. So, I was able to start work at 8:30 AM on Monday, Labor Day and I was done at about 11:30 AM.

I was prepared to use the A-M Gutter Guard Screws and magnetic Driver just to use the recommended product. But, apparently they are out of stock since it would have shipped a week later than the gutter guards. So, I followed some of the recommendations here in these reviews and ordered them as well.
"120PCS #8 x 1/2'' Sheet Metal Screws 410 Stainless Steel Hex Washer Head Fast Self Tapping Screws with Screwdriver Bit Silver" https://www.amazon.com/dp/B0BWN392S9?ref=ppx_yo2ov_dt_b_product_details&th=1 (Includes a 7mm magnetic driver which works great.)

Overall, I highly recommend these gutter guards. They are strong enough for whatever Mother Nature may throw at them and flexible enough to be reworked for the areas that might not be exactly as expected. And, they are cheaper than Gutter Brushes, which have to be cleaned out annually (at a minimum). At my age, I'm hoping I can avoid ever having to go up on a ladder again.
