I have a tall hedge and have used an electric hedge trimmer via a ladder in the past. I thought I'd try a pole trimmer to see if it makes the operation safer. This one cannot handle the larger branches that the more powerful electric trimmer can, so fast growing ash poles needed to be cut separately, otherwise this trimmer worked wonders. It has better reach and the angled head made for easier cutting along the highest sections. In the end I used a combination of my electric and this one, but for most operations, I would recommend this unit. Any negatives? A longer cutting blade would have been nice. It began to stick in the "on" position almost straight away, so potential safety issue there and I had to tap it sharply to disengage. WD40 cured that. Overall it is a very useful addition to my garden equipment.
