Anyone use it?

Opinion?

Can you run it in your gutters?

I`m looking at something like this:

I have 3 dormers with almost no slope, and snow and ice stay up there longer than I would like. Also the front of my house is 10' from super tall pine trees facing south... and snow stays there a while, not to mention this last COLD STORM we had I had 2" ice on my shingles after a melt and refreeze and I was worried my shingles were gonna get damaged.
