After speaking to a USB flash drive of FRITZ! had quite a few problems (several times a day disconnections, sometimes even after that then crashes on Windows 7), I then dare to buy these HAMA stick. At first I hesitated because some wrote here at Amazon that they would have problems with Windows 7. For me it worked right away! Not even the included software I had installed, Windows will automatically recognize the hardware immediately and installed the drivers. To date, ie for 9 months of the USB flash drive is running without a single misfire, despite very heavy use, often 10-12 hours per day. The DSL connection speed is also very good, the router receives a maximum of 8,900 kbit / s, the USB stick is then despite an intervening thick brick wall after all, still 7,400 kbit / s received. I am for peace high and can only recommend the device.
