These cordless hedge trimmer is really great. It cuts like butter in thicker branches to 15 mm diameter rigorously. The device is a real lightweight and battery-operation super easy to handle. The annoying tightening a cable or verify whether you risk no longer a cable cut - that relaxes the situation noticeably. So the work is really fun! The operating time of a fully charged battery (about 50 min) is sufficient for my needs. Unless you're working in a royal garden atmosphere, one needs also no second battery, which in my opinion is also very expensive. Perhaps the only drawback is the cumbersome locking the battery to the charger, but with practice you also get this handle down. From my perspective, this device is an example of pioneering technology and a target for all amateur gardeners who want to make work easier.
