This machine's vibration seems to be just as strong as any of the more expensive brands. However, because it lacks an arm rest, it does not target the upper body as much. You would have to shift and re balance your weight to feel the vibration in the upper half of the body. Although compact in size, it is a bit heavy and bulky. Aside from that, I would buy again.
I have been using the BOSU ball brand balance/vestibular dome at Physical Therapy. I love this one better. (And it was less expensive.) It is more convext than the BOSU, and so it really chanllenges your balance, and you can feel the muscles in your feet, ankles, calves and thighs firing to maintain balance. I took it to my PT appointment, and the Physical Therapy Tech, played on it most of the time during my appt. He was doing all kinds of exercises on it. It helps to stretch out tightness in my ankles and feet as well. I haven't gotten to do many other exercises on it yet, but can't wait to get them incorporated into my home PT/exercise routine.
