I purchased an Ab Doer 360 from an individual who bought it and never used it. I have been using it 5-6 times a week. I really like the way it works. The only problem is it has broken on the seat area twice now. And I have to take it to someone and pay them to weld it back. I paid a lot for the machine and I still have to keep putting money into it. It needs to be made with heavier metal. If it wasn't for the breakage, I would give a higher rating.
Bottom Line: No, I would not recommend this to a friend
