We used this on my wife's laptop to get an A/C standard instead of the built-in B/G/N standard. We live in an apartment with a lot of Wi-Fi signals from neighbors and their computer was periodically dropping the Wi-Fi signal. Setup wasn't difficult, and the Wi-Fi stability improved noticeably after installing her laptop. After about 6 weeks the USB connector broke so maybe not as durable as I would like but I ordered 2 more (one for my wife and one for me) as the price is so low.
