I have used this elliptical machine about 4 times a week for about 45 minutes a day.  It is great as I watch my DVD and forget I am excercising until the last 15 minutes.  You can lean back more, go slower to work the resistance.  It counts calories and time as well.  I used it and over 6 months lost 45 pounds and losing more now.  You can fold it flat and put it away in a close if you want.  You do not slip as there are ridges on the pedals.  I would recommend it to anyone and the cost was reasonable as well.  It works your arms, abdomen and legs as well.  I feel over all toned and healthy...
