Just got back from Portland, where one home had a mini orchard. That was the first use on multiple fruit trees. I pruned 6 apple trees, 3 pear trees, 2 plum trees, 1 cherry, 1 fig and 1 Turkish bay, all in 6 hours.
The Zenport electric hand pruner worked perfectly and never locked up. Used 1/3 of it's power, cutting with the small machine for about 5 hours and handsaw and hand pruners for 1 hour.
Actually, it's worth adding that two of the three battery indicator lights were on. Its possible if the unit were used 5 more minutes it could change to just one light showing 1/3 power. So maybe we can say it had about 1/2 power remaining.
