You will definitely get strong and buff when you work this tape, but BEWARE: it's not a good cardio workout and I did not really lose weight when doing this tape. I did, however, get very strong and muscular. That was very empowering. But I did not lose a lot of weight. My suggestion would be to alternate this tape with walking/jogging/running. And another thing, the side sit-ups made my waist thicker. So keep that in mind when doing the side sit-ups. Also, the side stretches in the beginning sometimes thicken the waist, too. Other than that, it's a fast work out. Do it if you want to get muscle. And what they say about her form is sort of true. Her form isn't perfect, but if you're in decent shape and don't get aches and pains easily, it shouldn't be too much of a problem. Just maintain the form yourself and realize she is doing it very fast. If you keep that in mind, you can just maintain the correct posture and form yourself. If you are used to doing one of the harder tapes from the Firm series, for example the Susan Harris tape, then this will seem rather easy to you. I do this tape when the prospect of doing the Firm is merely too much for me and makes me want to run under the covers and hide. On those tired days, I try a workout like this. That way, I am getting some exercise, but I'm not too drained. For beginners, this will be a hard tape, though.
