Yes, it really is that good.
Love this purchase.  I have been wearing an orthotic boot for nine months now, and began having pain again.  This device helps my foot to relax, and the vibration helps the blood circulation for better healing.  Although it has two modes, I only use the heavier vibration.  There is a dial that lets you adjust the intensity, but it is almost too uncomfortable at the highest setting.  The battery life is good, and the fact that it is cordless means you don't have to be near an outlet. I also have nerve damage from an accident that broke my neck ten years ago.  The way this thing works on my shoulders is amazing.  For me, it is worth the extra expense, because you can target different muscle groups with varying intensities for the most effect.
