I've had these installed for years and here are the pros and cons:
PROS: When these are installed properly, they will work in mild to moderate conditions. Cables need to extend beyond the eve into the gutter, and zig zag up the roof beyond the depth of the eve. You also need to hang a separate cable from the roof cable that runs the length of the gutter and down the downspout, or the gutter will just fill with ice and mitigate the purpose of the cable on the roof. You also need to turn these on BEFORE a snow event.
CONS: Tricky to install, especially when hanging the gutter cable (it needs slack). Count on buying more cable than you estimate too. I had to go back to the store twice. These don't work well in extreme conditions (a foot of snow or more or extreme cold temperatures - or both) They can make things worse if turned on AFTER the snow event (they just melt the snow and the water turns to ice immediately.) The shingle clips are designed poorly and don't hold well, especially if you use a roof rake (you will jut rip the cable off the roof, even if you're being careful) Your electric bill will be noticeably higher.
SUMMARY: This is really just a band-aid to a bigger issue (poor insulation or ventilation, or both) But they can be helpful if you have a low-pitched roof and have resolved all those other issues and are still having problems such as I do. Do they help? Yes, sometimes... Would I install then again? Probably not. I'd either find a better product out there and spend the money or buy a house with a higher-profiled, well-insulated, well ventilated roof - or move south!
PICTURE: This photo shows the cables NOT working well. Even though I turned them on well before the storm, we got 18" of snow in one day and it was -2 degrees outside. The cables can't handle it and I wish I hadn't turned them on because I feel like they made things worse. The last small storm we had, they worked much better and I had less ice and no icicles.

Great to have, just an FYI
Works great!! Just FYI to other installers make the spacing 5" not the 7" they say in the instructions helps under thicker snow and ice.

Product broke
Bought in Feb 2021. Installed in Fall 2021. Worked for the first couple snowfalls, but now does not warm up. As of Feb 2022, after the recent 8” of snow the product is no longer working. Basically the product broke during the first season of use and I can not do much about it until the spring. Likely past the maximum return date for Home Depot, so may try to send back to Frost King once I can remove them.
