I bought the scissors last year for use on 200 olive trees. In a few words, it is amazing. Its main advantage is its battery, which charges in 1 hour and lasts at least 10 hours (I didn't test it further). (The lithium battery and the bag are included in the price). It has electronic indicators for everything: charging, small and medium pruning, large and small head adjustment, remaining time, and even a counter for the next service. The blade of the head must be of very high quality - I haven't needed another one so far (we're talking about 40-50 sharpenings until now). It needs cleaning of the head every 1 hour or so and a little sharpening to work perfectly. The blade can even cut 40mm dry branches effortlessly. It has a maximum blade opening of 45mm and a convenient direct adjustment for 50, 60, 70% of its opening. From what I researched, the manufacturing company (Swiss Felco) has spare parts for decades, and I believe it will have them for just as long. It costs €1430 and is worth every euro (I bought it in installments with a good discount). Swiss quality. Science in pruning...
