It's a cheap piece of crap that works fine the first time - and
deteriorates with every use untill it is useless before finishing
trimming an average tree.
I've worn out (sprung) several of them - then I got a couple with
cast aluminum heads. They didn't deteriorate gradually like the steel
ones, but working them too hard I broke the castings.
I have since found a GREAT unit - a straight jaw type from Lee
Valley. I guess the official term is an "anvil" pruner, as compared to
a bypass trimmer. It cost me about $50 but it will last me a LONG time
- and the pole is aluminum extrusion, not flimsy fiberglass.
I also got myself an electric pole chainsaw - tried it on the cherry
tree on Saturday and it was a real treat - went through 4" branches
like butter. (8 inch bar)
