For 5 weeks, I have the Bosch AHS 54-20Li cordless hedge trimmer and cut thus far about 120m privet hedge with a height of about 1.50 m. With the result I am very satisfied. 50 m you can cut loose on a single charge. So far I have been working with a wired Bosch hedge trimmer, which also performed good services. The battery shears is easier to handle and there is no danger to sever the cable. The weight of the battery scissors is also smaller than in a power supply unit. I can see the Bosch cordless hedge trimmer AHS 54-20Li highly recommend. M. Bergner
