Too tricky for me . I have Jennifer's Crunch Salsa Dancing DVD, and it was my first dance exercise DVD.  I loved it so much I've been ordering a lot of others and ran across this one by the same instructor.  I find the moves too difficult and frustrating.  By the time you are close to having one step down, she's moving onto the next one, and it doesn't seem like you get to benefit from the repetitous moves that I enjoy in her Crunch video.  In that one she started out slow, repepated it several times, then did it real time, and then added another combination the same way.  The end result was putting the two combinations together, so basically repeating four moves over and over, doing about six dance routines all together, which was good enough for me.  When I do it now, I just go right to real time and ignore the slow start, so I haven't been bored at all.  She looks great in this video, but I agree with another review that they do not focus on her feet at all.  Basically I ended up watching her dance and kept marching in circles.  But if I was a good dancer, this would probably be a lot of fun.
