Not knowing to choose a wireless solution between a wireless network card and wifi usb key, I finally opted for the key. Why? simple: no need to disassemble the computer to realize that there is no adequate port to the NIC. Given the abundance of wifi usb key solutions and especially the prices ranging from one to three, I opted for this one and frankly, in 5 minutes, watch in hand, I have a PC that runs in wifi fire god without losing speed, quite the opposite !!! it surpasses my old NIC and it shows on. Beefy product for a mini price: it's simple, I never removes desktop pc nor disables and everything turns as if nothing had happened. No problems "disconnect" as seen on some forum with other products. Hoping that my opinion could decide some who are still undecided: for the price, you lose nothing! you gain in quality.
