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 am very petite, so this chairs fits me well, but I'm certain it would not work for someone over 5'10" or so. I use it for my art work and it helps me balance and keep my back from straining. Love it.
I am 76 years old and a health nut and exercise enthusiast, always looking for products that improve my health and physicality. This chair assists me with my posture and core conditioning. Love it.
