Didn't like that it didn't sharpen knives as well as I was hoping.Nice having kitchen knives sharp againSharpener binds up with any pressure and doesn’t sharpen knives very well.no sé sostiene muchos y es muy frágil las cuchichas lo bueno es que afila muy bienIt was pinched. Cut wire had shortageease if useThis unit lacks power for sharpening your cutlery. In order to sharpen your knives you must go slowly otherwise the motor begins to slow down considerably and it may even stop the sharpening stones, which don't seem to be the best either.The product, at least the one I received, while easy to use, doesnt hold the charge that long and must be immediately recharged after use. The motor isn't that powerful, requiring more than 2-3 passes before seeing only a slight difference in sharpness. It's and okay product for the price, but I would look elsewhere first.This is a great little machine - I didn't realize how dull my knives were.......a few passes though the coarse wheel, and a couple through the fine, and I'm slicing tomatoes without squeezing them, and roasts without it looking like a massacre. I have mostly mid range knives, and one high quality carving knife - worked like a charm on all of them!It charges quickly, and its compact, so you can take it with you while visiting and others can share the joy of 'new' knives!Very poor product. Wireless it is but no power. 1 and half minutes and no power. It would’ve been better if it was wired. Charging from USB takes a long time and battery power is just too poor. Very unhappy with the productOUF! je retournerai cet achat, insatisfait, n’aiguise vraiment pas les couteaux de plus manque de puissance etc.L'aiguisage n'est pas concluant. Le moteur est faible. C'est un gadget inutile dont je regrette l'achatPas assez fort j’en ai acheté un qui va dans une prise électrique et non une prise de téléphone
