Indeed thank you Amazon who assured customer service. When I received this mower I wisely followed the manufacturer's recommendations for charging the batteries several hours before first use, result 5 min run at the most and then nothing. Brief having quickly realized that my article was defective I immediately warned that the Amazon has exchanged me almost saw it take to write ... Once the new mower réceptionnée I immediately used without any "first battery charging" as advocated and everything seems to work. However I'm still a bit disappointed with this product which is actually not better than my old Philips trimmer (12 years of age) and barely even cutting once the density of hair is important (those my boys not mine unfortunately). So no more 2 stars for this article but 5 star Amazon that is always with impeccable customer service.
