I have been using one of these dongles for over a year now as it was bundled with a router, and, while it performs reliably, I would not recommend it.
The main problem is with the driver, which uses unintuitive and proprietary Netgear software to configure WLAN connections. The most annoying thing about this software is its constant desire to try and connect to BTOPENZONE-H access points instead of the configured Netgear router.
The dongle has worked well since switched off the Netgear driver, but as a result of the problems, I would not recommend this dongle for a beginner, and even for advanced users, I would recommend getting a dongle from another manufacturer.
