I have the Fiskars pole pruner and use it a LOT, I think mine is 11' or so...DITCH the saw blade it is useless.
Other than that it is one of my most used and useful tools for pruning, I've had mine for about 3 years and it is doing fine. It gets dragged around in the trees a lot and abused, dead branches and twigs get banged with it...then live ones snipped and clipped. Max branch size you can cut is about 2" for real soft stuff, less for harder stuff
The multi position for the pull handle is great, keep it short and use the sliding one in the middle, extend it all the way, reach as high as you can and use the knob on the bottom...the swivel head allows you to make more precise cuts too. The 'cord' is actually a nylon strap, it lies flat and close to the pole and so doesn't get tangled in the branches.
If you want a pole saw option, get a Silky, I've got the 21' Hayauch...light enough to climb with, doesn't require popeye arms and shoulders...my blade is still good after two years...
Have a Fiskars (actually two, got the 6' stick as well) use it a LOT, like it a LOT!!
