After some research, I chose this item, cuts branches about 1.5 inches (approx) very well when standing on the ground, easier to control when extended up to 12 foot high. pulling the drawstring work well.
However, when using all the pieces, reach 26 foot high, I managed to carefully get the pole cutter to sit on the branch but was unsuccessful and unable to see if I had the cutter in a good position to make the cut, very difficult to control, tried about 4 times to cut one branch and failed. Might have worked better, if there were two people to control it, when it is 26 foot high. Despite this dilemma, I am still happy with my purchase, it works well when trimming branches. Excellent value too, bought for £49.95 a few months ago.
