This cable is awesome! It charges your phone while you transfer files. The only problem was the software. You have to go to their website and get the latest version and make sure it's for the correct model phone. We had a little trouble setting it up at first, but we didn't have the correct drivers installed for our model RAZR. My boyfriend and I are each on our 2nd RAZR phone and we've been making ringtones and transferring photos for 3 years. Now US Cellular charges $13 a month per phone to have access to download ringtones. That on top of the cost of each ringtone? You do the math. I paid $17 for something both of us have used for 3 years and have had a blast with.
