My brother just had one and we were all amazed at how great he looked and how quickly he was feeling so well. I don't know any of his details though. We even laughed that he lost weight even though, in his words "I've done nothing but sit in a recliner and watch Storage Wars and Amish Mafia". We think it was due to less trips to the fridge for snacks. He also laughed that he now has to look to an exercise bike rather than a treadmill for his exercise, and he assumes that will lead him to want to get a bike to ride outdoors too, so he was asking our sister and I things like "do I HAVE to be attached to the pedals like you guys are?" Long story, with no details for you, but a positive story in that he's doing really awesome!!
