Review on Efficient Roof De-Icing: HEATIT Spacer and Clips Kit for Heating Cable by Jon Garcia

Can't believe other reviewers didn't point out that these clips don't work. First, when trying to get it under the pavement, the Pebble bends and distorts the clip and notch, after which it won't even hold on to the Pebble (it's crappy aluminum, for goodness sake). Second, the part that holds the wire is so thin and flexible that I seriously doubt it will hold the wire in heavy snow when the snow rolls off the roof. What a big disappointment. I am returning the order. If it were stainless steel like it should be then they might work.
