Okay. My mom bought me one, maybe a month after my dad died, along with one for herself and one for my sister.

I tried it. It didn't improve my balance at ALL... in fact, it made me feel drunk. And off balance. Seriously, drunk. It was the only change I made.. wore it for a day and a half, felt really weird and wobbly the whole time. Took it off and felt better within a couple hours.

It was strange. My mom returned all three of them, but I was the only one to notice any kind of effect.. positive or negative.
