After a couple of high $ bids from tree pruning services we invested less than $100 in this tool, which did everything we needed. The length of the segmented pole is increased as needed by adding segments, which is very easy to do. there are two different tools that can be installed on the business end of the pole. One is a conventional bypass pruner actuated with a rope and a short saw similar to typical hardware store pole saws. The other is a larger saw blade with a hook at the end. This blade is very well designed and functional. With this we were able to saw off a 5 inch diameter branch at more than 20 ft elevation without climbing or standing on a ladder, and smaller branches even higher. At the longer extensions the tool gets a bit heavy. I am 76 and in ok shape, and could use it up to about 18 ft extension. My son is stronger and could use it at full extension with some moderate difficulty. Overall the tool is very well designed and constructed. It comes with a spare hook type saw blade and a nice carry/storage case. It is easy to give this 5*.
