Regarding the short side of the mower can be not to use sabots.On can not use it for finishing to trim the edges of their beards but not for mowing small areas at a desired height.
The device, when held in "reverse", razor in good order. Independently can be switched on and alternately one or the other.
It was well in hand 2 see 3 devices to take care of his face to shave his beard and mow performing finishes.
Regarding autonomy: without comment just fine for this type of device. I did not value to on this plane there, except that start indicator will indicate when the mower is running out for not surprises.
By cons on the burden of the machine, then this is a little disturbing to me, there is no outlet for connecting a charger !! Si Si. In fact the charger must be connected to the support (to store your camera vertically on your bathroom furniture) and the equipment on its support for it to recharge. You'll understand that in case of power failure you will have no choice but to wait until your device is charging in the cradle again before you can use it.
Apart from this last small point, I am quite satisfied with this device.
