It would be great if your gutters were already clean and didn't have the 2" of wet leafs and sticks that they normally have. Most of the fancy tract house builders around here use 5" gutters it would never fit. I wouldn't give $5 for one. Kinda like the amazing garden weasel. They will sell a ton and they'll be in garage sales for the next couple of decades.
I clean about 1200 gutters a year in a retirement community,the key word in the ad is "out" not clean up. Consider the clean up time after. A cute looking toy. Thats all. Dan Cosgrove
