Rope saw - chain saw on a rope for limbs

[scuba_dave]

Has anyone used one?
I'm looking at buying one
I have one limb from a neighbors tree that overhangs my yard. Too high for a ladder
For $30 seems like a good deal, even if I only use it once or 2x

Is it too high for a pole saw? Mine reaches about 16 feet. I use mine on my 8 foot ladder to cut even higher. The cutting power comes from the weigh of the saw and pole as long as you don't cut directly vertical. I've seen the rope type chain cutters but never actually used one. It seems like such a wide kerf would require a lot of hand power and now weight helping the cut advantage...
