function free device

I only needed a scanner to scan documents. Of course, I then pick a not very high-quality product.
The delivery was fast, we will see how it is with the refund.
In return, the installation did not accomplish. In the first attempt Windows7 took over the installation of the drivers, I installed the user software from the supplied CD.
In the first attempt to scan a document carried the message that no drivers installed.
Okay - on Device Manager tries the driver update procedure is interrupted because drivers will be current and the device reportedly is working properly.
Second attempt:
Drivers and user software uninstalls, removes all traces and device reconnected.
User Software installed on CD - allegedly the drivers are installed.
Tries document scanning - Error message: see first attempt.
Installer used the drivers for Windows7 (32).
So try to manually install the drivers (64) - no chance, because the manufacturers software a complete reinstall with the (32) - makes driving ....

Result: Angry the unit packed again and wear it after the post office.

My recommendation: stay away and would rather spend 10 more.
