Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

Built-in RTL8191SU chipset - 1T2R - TX up to 150Mbps and Rx up to 300Mbps;
Well built with a strong enclosure and nice brandless all piano black with a discret blue led design;
Interchangeable exterior antenna (the bundled antenna is good enough for any domestic or SOHO environment);
Plug&play with full "n" speeds in any modern Linux distro;
Good drivers support from Realtek;
Very stable connection both in Windows and Linux often peeking the maximum speeds (Tx=150Mbps / Rx=300Mbps) at approximately 25m (indoors) from the AP.
Very well packaged including accurate and compreensive specifications in the back.
The price is fair and average for this type of devices but could be a little lower.
However, from a stricly technical point of view there are ABSOLUTELY NO FLAWS.
Besides its excellent performance tested with a uptime of more than 15 days in a row it's detailed package is worth mentioning: Much better than almost all mainstream brands I could find locally.
DX should correct the product overview/specifications in this page. The Realtek 8191SU chipset is 1T2R. That means the transmission rate using only one antenna is limited to 150Mbps. The reception rate uses both the external and the internal antenna (in the PCB) thus achieving a reception rate of up to 300Mbps.
You can't go wrong with this one.
