Little things like the sound buttons are certainly bearable. However, a faulty radio link can drive you crazy. So letters late or not transferred to the keyboard again. In order for a flow of writing is impossible. Sign I had to re-enter again and again, a reaction was carried out until at last. The mouse "jumps" and responded sometimes not, but then extremely imprecise. To make the point X, I was nervous about it times, then under it. The solution: If the USB receiver (such as a USB flash drive) REAR plugged in the computer, the wireless connection works well only inadequate. Although supposedly yes up to 10 meters ... Put the embroidery on the front in the computer, or by extension on top of it, then everything goes quite well. Whether I can live with that, I do not know yet. Currently I am considering returning. Even my ALDI keyboard + mouse ran as better REAR plugged into the computer.
