"The Concept ll is a rowing machine reenacting a row boat, kayak, playak, or canoe in the water. However, the work-out isn’t as strong as the real thing. This is due to the density of air being 1/800th of the density of water."
"Surprisingly, there is no work-out on any part of my legs. This is because the point of using the machine is to pull yourself, not spring off using your thighs."
"One disadvantage is that there is no back support my back got very sore after using it."
"Why would you pay over $700 for such a weird looking machine when you can pay $200 and get a Total Gym that won't disappoint you. This machine is trying to do exercises somewhat close to Total Gym but not even close. If you really want to buy a good exercise equipment that really does work then you should consider getting a Total gym or Bow-flex. Those gyms won't disappoint you."
"...was sorely dissapointed in it when I went over to [a friend's house] to see how it works. It has very easy difficulty settings, so little excersize is gained by using it. Also, it is big, loud and ugly - not something you would want to have in your house. It does not hold up well either, it already had dents even though it was only a month or so old."

If you go to this link, don't be fooled by the backpack thing pictured. Or maybe some of these people expect it to function as a backpack?
