We live in a townhome and purchased the LeafFilter solution. It works just fine for roofs without channels, however, if you have one they need to install a Channel Guard. This will stop the water from running over the LeafFilter. Sounds good but in actuality, this is where stuff gets stuck, then the overflows happen. I had to go out and buy a leaf blower with an extension so I can reach up and over the guard and blow whatever is stuck up there. I use the leaf blower at least 2 or 3 times a week during spring and fall when there is a lot to get stuck. If you have channels on your roof, don't purchase this product because it's not as advertised in this circumstance (and of course they don't tell you that).
Bottom Line: No, I would not recommend this to a friend
