The box in question is a good idea on paper, but poorly made here. Too large to be practical on the move, it has, inside extra storage honeycombed recycled cardboard, which is certainly not intended to be kept beyond the initial unpacking. And once this retired cardboard, all accessories are wandering in the box, now for once, useless (and not a penny for ecological, 100% cardboard packaging was finally better ...) A simple washable cover was more useful.
Manufacturing quality side is just okay, considering the price. The design is successful, but we did not seem to have in hand a very robust device. However, the warranty can be extended to 5 years by registering with the manufacturer.
To be entitled to a more powerful battery than NiMH, we must examine the top model HC7450 / 80 - which also features titanium blades against conventional steel blades of this model HC5440 / 80 (see also HC5450 / 16, almost the same price and that these titanium blades, but not Li-ion battery.)
In use: (. No lubrication required) good effectiveness as a hair clipper, good grip, easy to adjust (24 cutting heights), easy to clean too since this mower is sealed, maintenance is reduced However, the use as a beard trimmer is hardly convincing. It is not advisable as most body mower, but it is true that it is not intended for this use.
