To my amazement, I found The Bean at my local Walmart (which typically doesn't carry many newer fitness items). I'd been eyeing the infomercials, specifically when they talked about easing lower back pain (plus ab strengtheners also help with that) so I got it. I haven't used it a whole lot, yet, but from the workouts I've done (the back stretching and strengtheners and relaxation) I think it's going to work for me. Plus, some of the stretches are really yoga poses (pigeon and child's pose, for example) that I love to do, but because of my injured knee, I can't always take the pressure of these poses on the floor. However, doing them on the Bean takes the pressure off my knee, so I can do them with comfort now.
So, yeah, I could've lived quite well without ever having The Bean, but to me it's worth it ($48.88 at Walmart)--and I haven't even done all the workouts so far. It seems to be pretty versatile, and it's not as stable as it looks on TV. Some balance is required in some of the exercises/poses.
JMO,
