Not for a long use.

It is usual practice. As soon as you buy thing, they want you to give positive review almost right away. It is wrong. I bought this sharpener almost a year ago. First, it worked good, in 2-3 month it was not so good (did not sharpen pencils as it was promised), in half a year it worked already "so so", and finally it broke down. That is my general experience. And believe me I did not use it too hard.
