Negative Positive
Title: Worked great for 1 month/horrible customer service
Review: I've owned two previous Rio's that I really liked and were adopted by my kids. I upgraded to the Carbon. It worked great for one month then required that I format the hard drive every time I wanted to add/delete music. By month two the "permanent" long life battery was dead. I followed the exact instructions on Rio's website for warranty assistance--THREE times and was completely ignored.
Is the review positive or negative?
