I used to have one of these (ok it was a different brand), but the same product. I though wow, just a few minutes every other day and I'll be toned and trim. Ok, I'm not overweight and did buy it for the toning aspect more, however - It didn't seem as though it was doing anything, and I most certainly didn't see any results. I think the most exercise it gave me was from dragging it out into the centre of the room - It weighed a chuffin' ton! ...And boring? OMG! 5 minutes on it seemed like 5 hours - I couldn't wait to get off it and lug it back into the corner (again, the only decent part of the workout!) Get an exercise bike or cross trainer and bung it in front of the telly that's what I say!
