Had this for almost two years before I needed to load it (as you understand it was used extremely sparingly). When I tried to charge it, it refused to accept charging. I then tried to make a complaint, but before I returned it I tried to charge one last time and then suddenly it received charge. Maybe I used a USB cable, don't remember. Either way, it is the same thing now, the device does not accept charging.
Moreover, it now doesn't work to cut either. It seems like the knives are out, even though I barely used it. Has screwed apart and cleaned and lubricated all moving parts, but it doesn't get any better. May try to complain again. DO NOT BUY!
