First time I use this kind of device, and I regret not having bought a lot earlier, because I'm more hairy ears and nose .... as elsewhere.
A small flaw immediately, a priori, is that we need a battery to operate the device. But first attention of the manufacturer, the battery (unique) is provided! It will verify the long term, but I think that the consumption of this kind of machine is small enough that this battery lasts a long time, and basically it's better than spending his life seeking the charger!
Second nice touch, the number of supplied accessories. Not sure I will use all, but hey, who can do more can do less, so a single device such as this can have multiple uses depending on who uses it, so why not.
Third lovely touch, the small carrying case, discreet and effective, which will carry the mower and Useful accessories, with discretion and without taking up much space, maintaining a good level of cleanliness.
Finally, cleaning operation very simple and effective, so really a perfect tool and much more useful than nimaginerait perhaps, deserves its 5 stars, especially for a near ridiculous price. Great gift idea!
