Actually I bought the cable for charging only, but after I had read in a review that it is not suited for data transmission, I had to try it, and I have to say-it works flawlessly with my LG Optimus Speed.Der micro- USB port is very tight to the phone, but what I personally find advantageous because in my original connection cable to the connection often times loosens unnoticed, and I realize in the morning that the device wurde.Das not reloaded now belongs to the past an.Kurz I am completely satisfied, the price-performance ratio is excellent (specialized trade 18.99 euros), and the cable is both for charging as well as for data transmission geeignet.Ich it can recommend with a clear conscience.
