After I saw the price (daily price 22/11/2012 - EUR 37.99), I thought to myself, there are better and cheaper alternatives determined.
Asked the best friend -> google.de - who always knows everything.
So I was alerted to the following page:
[...] There are the following models to choose from:
TP-LINK TL-WN721N TP-LINK TL-WN422G v2 Netgear WNA1100 D-Link DWA-126 TP-LINK TL-WN722N Unex DNUA-93
I opted for the TP-LINK TL-WN722N. This stick is a bit greater than the ONKYO dongle cheaper but by far. Nearly five times cheaper.
The this in the color is white, does not bother me. He is hiding behind the reciever.
Have paid 8.00 EUR (incl. Shipping). The drive performs good services. Can only recommend as a cheap alternative this stick.
Others I have not tried. Nevertheless, this device is worth the money. For 5 out of 5 stars.
