I put 5 stars for the 3000 Microsoft keyboard because it is beautiful and in addition it works beautifully. The only small problem, but I would not put down into stars is that for the F1 through F12, it is not registered but the keys directly above and Blue, in broad daylight, but it will when it is dark, you can not see the F1 to F12, which is a shame. The keys are nearly silent otherwise. Apart from that, I find the impeccable and I recommend it anyway because beautiful and works nickel.
