I bought 3 of the 101's using the code. I bought Jan, Feb and Mar. The sound quality is poor. The dvd's are echoey, you can barely hear the music and you know what? I still love them! The workouts come in at 30 minutes and are still tough. I find them more manageable than her volumes sold thru mary. I have Volumes 1, 3 and Bootcamp. The 101's are more manageable in terms of time and level but are still brutal for me. I am really enjoying these.
