I bought this to place a USB wireless adapter away from the computer, to get a better signal from a remote router. It seems to work perfectly, giving me a reliable connection with good bandwidth where previously I had difficulty connecting. As you would expect at the price, the cable and connectors are of just basic (but entirely adequate) quality. The cable is actually longer than 3m, which suits my purpose, while there is no apparent loss of performance due to it just being passive (longer cables often have active amplification). Overall I'm very pleased and can recommend this product.
