I've been using it consistently for a month, alternating with a few other workouts in between. It has grown on me, bad cueing and all.
I do the cardio portion twice, then the weight portion.
As far as 'results', I'm never sure exactly what that means, since each of us has different goals. That said, a bit of background: I have been trying to take off a few pounds, and I have found in the past that if I ramp up my workouts too much in an attempt to burn more calories, I end up so hungry I defeat my own efforts to eat more sensibly. I have been pleasantly surprised to find that my method of using this set has not made me hungrier, and I am so far successfully losing weight and also achieving strength and tightening of my muscles.
I do modify a bit, particularly for the gliding on the floor dragging planks. I hate them, to put it simply. Burpees are a pleasure compared to them.
I don't think there is too much horizontal cardio, at least not IMHO. The weights I use are comparable to those used by Cathe for the most part, and in order to eliminate constant switching between barbells and dumbbells, I use only dumbbells. I lighten up for the overkill on the shoulder and bicep sections and that works for me.
I may be in the minority, but it's been a good purchase for me and I'm glad I got it.
Hope this helps!
