Input:
I found this product to be exactly what previous reviewers had suggested.  It was delivered in a few days with shipping free.  It was easier to put together than some people suggested.  I'm not real handy but it was much easier than other products that require assembly.  It is very easy to use and has really helped my back.  I am a runner who has been at it for 35 yrs.  I have a bulging disc and the inverting table has really helped my back, hips and legs feel better.  I have only been using it for about a month and time will tell if it continues to help but the immediate effect has been very encouraging.  I invert for a few minutes every morning and again before going to bed.  The only downside is the ankle holders.  As previous reviewers accurately stated, they are uncomfortable.  Heavy socks and/or shoes help to tolerate them but they are still irritating.  Bottom line is that for this price you can't beat it.
