At first glance, the keyboard makes no so bad impression, until then puts it into service. The entanglement of the keys makes one mad after a short time. I'm only starting from a defect of my keyboard and had them replace the supplier. Unfortunately, the second keyboard was not any better. All in all, I have the 20 quasi thrown out the window, because the keyboard is not even fit for the sporadic applications for which it was provided.
So rather spend a little more money, is favorable here unfortunately equal cheap.
