Effective for High Branches, Though Costly

This polesaw is a costly option, but it provides a safe way to trim higher branches when no other safe method is available. It performs well for that purpose. The main drawback is the price, which is high, though comparable to renting a boom lift. Overall, it does a great job for reaching and cutting elevated branches safely.
