When your hedge grows too thick for my 12 year old Ryobi 240V EHT750 I did a search for something more capable of cutting 20cm thick branches. Dewalt surprised me by easily clearing thicker branches. It appears to be easier to balance and handle. Battery usage appears to be quite good. the only downside it seems a bit more noisy then the old 240Vac unit.
I'll update the review after few months of usage.
