I agree with what was said in the earlier review. My own comparison is with the 10 year old B&D 22" electric that it replaced. I was impressed in that it gives up nothing in terms of power. I used it today for the first time on my 150' of hedges and lots of other bushes, especially hugh forsythias. It did all the trimming with no sign at all of battery fatigue. It's much smoother in operation than the old one. There are two things I didn't like about it. The forward handle is made so that it's only comfortable to hold at the top and not at the sides as in the old models. Also, as was said, there's not a lock-on switch. You have to hold the switch on. They did that, no doubt, for safety reasons, but that's probably where the fatigue enters. Many folks will rig up a clip to achieve the same thing.
