I have always used Verbatim CD-Rs, but this is the first time I've run into trouble. So far, I have gone through 10 CDs - zero have worked in my car, two have worked in my fiance's car, and ten of them have really pissed me off. Unfortunately, I did not test these out right after receiving, and now it looks as though the return window has passed. I'll pass on Verbatim next time.
