Mower highly effective, powerful, perfect cut in one or two passes, light and handy. Autonomy is more than satisfactory, we can make several cuts in a load. I mow the hair of my husband who has thick and supple Hair, therefore 90min 10-15min with battery, not to fear failure wireless. The cutting head can shave quite closely with its height of 0.8mm min. This trimmer is also quite silent, which is far from the case for all, we can talk and even watch TV or videos at the same time! We are very satisfied!
