Query: Not for the beginner

This CD is not for anyone who hasn't had previous experience with Czech. I find Czech rather challenging to pronounce, which is why I ordered a CD, but this one is not at all helpful. It gives very few basic words then takes off into long phrases that are impossible to repeat in the time given. Nothing is repeated. The speaker speaks quickly, which might be natural, but does nothing to help the student pick out individual words. Since I opened it I can't return it, but I'd like to. So, buyer of CDs beware. Once they're opened, you're stuck with them.
