Anyone use an inversion table? Thoughts?

Just wondering if anyone here has used an inversion table (pic) and if they liked them. If so, please elaborate. Our local Sam's Club has them for about $140. They sell for $168 online but that includes shipping.

I've heard of some of the horror stories, such as bursting blood vessels in the brain but I can't help but think much of that is urban legend.

 

I have used gravity boots for years and there is nothing wrong with me....sort of...well nothing from the gravity boots . Seriously, I am not an MD, so I cant speak to that, but it helps my back and knee pain. I dont know why the knees though. Thats a good price, they used to be $3-400
