I have the Ultimate Boot Camp Challenge tape. The quality of the video is not that great but it is definitely an intense video. It's filmed outdoors. I haven't done it very often because I usually workout in the morning and on one section she has you run around your house for a few seconds. That is hard for me to do when everyone is sleeping. It is definitely an unusual video but very intense. Mindy and Cathe are pretty close in intensity IMO. Video fitness has some pretty detailed reviews on this one - http://videofitness.com/reviews/mylrea-ubcc.php
IMO, it's definitely worth $10.
I have her Awesome Strength video. It shows different variations of the exercises with different equipment so it's really cool and very challenging. I give it two thumbs up.
