Rated 3.0 out of 5.0 by Could be better Pros: Sturdy metal construction. Easy to install. They fasten easily and really stay in place (not worried about winds blowing them off). I haven't used them in the winter yet, but I think they'll be fine. Cons: The mesh is just large enough to keep out leaves and twigs but not small enough to keep out maple seeds. They stick straight up and look terrible. I have to vacuum hundreds of them and eventually glue down a finer mesh over top to keep them out. It will be another project. (Ironically the mesh I will be gluing down is coming from the old Amerimax plastic gutter guards that wore out. Why they didn't apply the finer mesh to these new metal ones is a mystery.)

Rated 4.0 out of 5.0 by Easy to install, no-brainer choice. I took home one of each gutter topper that Home Depot had on the shelf (6), and put them side-by-side over a long run easily reachable, thinking that I would wait a month to see what was best. Looking at all of them after they were installed, it was a no-brainer. These tucked under my shingles easily, and locked perfectly onto my 5K gutters, keeping the same slope as my roof to the edge of the gutter. They are virtually invisible from the ground, sturdy enough to not droop, and look like I could easily flush out what does make it through (dirt and shingle gravel I would assume) with a hose without having to remove them. I have 225 feet of gutter on my 2 story house and had them all installed within 4 hours, sliding them between the paper and shingles, trimming as needed, with a 1" overlap. I even removed my downspout filters because the mesh on these are smaller than they are (why inhibit the drain?) Now only time will only concern is that the holidays are quickly approaching and now have to re-engineer the gutter mounted light mounts.....(anyone have any ideas?) October 27, 2013
Rated 4.0 out of 5.0 by Verdict still out I have a large oak tree at the rear of my house and fills my gutter in a few weeks. Although I can get on a 10 ft step ladder and using my Ryobi battery leaf blower I can clean them out. I am 70 years old so long I am needing a long term solution so I do not have to be compelled to clean them so regularly. The gutter guards are well made and easy to install. The disadvantage to me is the gutter hangers are on 24 inch centers and the guards are 36 inches so I have to cut a notch in them where they lay on the hangars( tubes and nails) This slows installation. I could cut them off but I would be wasting a lot of material. I use tin snips because these are tough. This slows installation and creates the situation where the ends of the guards often line up between the gutter hangars and might droop. After installing about 10 guards on a windy day I noticed the oak leafs were getting stuck in the guards, the leaves have short stems on them and the stems get wedged in the grill work on the guards. I stopped the job 1/3 way thru to evaluate how much this might affect their ability to shed the leaves. My concern is the leaves will pile up and block the water from the gutter. I may have to return the remainder of the guards if they prove impractical. January 30, 2014
Rated 5.0 out of 5.0 by Excellent and good-looking product! The powder coating on this was very nice and uniform. It was simple to install but not as easy as I thought it would be but perhaps that was just my particular installation. Once I figured out how to get them on it went much quicker. They were easy to cut with wire cutters to cut them to length or get around corners, etc. December 10, 2013
Rated 2.0 out of 5.0 by Too flimsy to hold shape Installed easily but collapsed into gutter after only a few leafs blew onto them. Woks great if your goal is to trap debris inside your gutters.The instructions said to rest back portion of screen on the back edge of gutter. The problem with these screens is that they are to flimsy and not ridged enough to maintain their shape, so they fall into the gutter. October 27, 2014
Rated 5.0 out of 5.0 by Clean your gutters for the last time!!! This item is the best kept secret in gutter cleanliness. Clean your gutters one more time and then install these little guardians of nature. Might have to start a little side business offering and installing these! January 7, 2014
Rated 5.0 out of 5.0 by Well made, easy to install I installed 150 feet after purchasing a few test pieces. As I installed each piece I found that my gutters deformed a bit from the weight of the ladder which caused the installed sections to move slightly. I suggest that you use something like a long barbeque fork to reseat each previous section, as necessary, when you install the next section. I used the fork to grab the grate of the installed section and pull it forward to firmly grab the top edge of the gutter if it moved out of position. August 12, 2014
Rated 4.0 out of 5.0 by Better, but not best Easy to install and do the job reasonably well, particularly for pine needles and leaves. However, unless gutter is without flaws hard to hold screen in place to allow for linear one line appearance. August 26, 2014
