I agree that the step system is hard to shift out of the way since it comes apart easily, but I am amazed how it stays together no matter where you step on it. As far as it being too small, maybe the other reviewer is too big. I'm 5'11 and 180 lbs, and I use one raiser level, and it is perfect. Everytime I use the dvd (which is energetic and even a bit challenging at first -- and I had done step class at the gym about 10 times before purchasing this system), I sweat so much and my heart rate is elevated, so I know I'm getting a great work out; I recommend it -- especially to those who don't like working out. Easy to follow, repititive, but you feel like you're accomplishing a good fitness program when you finish!
