Seems good to use, but ultimately it is only the quality resentie, the "return" key is stuck in the down position after 4 months of use. The keyboard is now unusable. I have no possibility to obtain warranty on my amazon account. or else "demand guarantee" function is very well hidden ... By cons, to post a comment, no problem, it is simple to find. I put 2 stars, because when the keyboard worked, although it faissait his job anyway.
