The Eumex 402 was 1nen day after the order for me, this is great Amazon. Unpacking, Connecting, PC install, this is all in 15 minutes. to create, even for someone who has never done this. For the establishment about 5 minutes. and everything works immediately. Windows 8.1 also had no problem. The only drawback (but is not a star) is the size of the power supply if it but that's why last 10 years, it is all right with me. Would take any time
