Received this mower early January 2015 and after correctly made the first battery, I just made my third cup today (4/12/15) still on the first charge. 3 cups in 4 months on a single battery charge, it's right up there with my old mower (Babyliss), I had to recharge it before each cut. The lawnmower is very well equipped with 10 cutting blocks (3 to 40mm) for one size. The shoes fit perfectly and no risks they do not remove or move unlike mowers with multi-size shoes. The mower cuts perfectly, do not hold in the hair and is not very noisy. Another plus: The mower is delivered in a small suitcase, with all its accessories (shoes, scissors, combs, cutting oil, charger and cradle and small brush for cleaning), ideal for storage and transport.Honnètement for the now I do not see any negatives to see over time. I am not a hairdresser but I think for home use this mower is perfect and highly recommend it. Mower semi-pro high performance at reasonable price, why not use it? Fast and consistent delivery.
