do I send it back or not?
-1 star.  The description and instructions are in some language that initially looks like English, but on closer examination seems translated from Chinese (?) by someone for whom English is a third or so language.  (As are a couple of the other reviews.  Friends of the manufacturer?)<br />-2 stars.  The straps pull my shoulders back some, but I can walk with my upper body leaning quite a bit forward and it does nothing to help my head straighten up.<br />-3 stars.  When I sit down, a moderately frequent occurrence, the stiff back pushes up against my my neck resulting quickly in a neck ache.<br />-2 stars.  I am instructed to give this product a 5-star rating because if I have a problem and call, they will certainly fix it.  I don't think so - they'd have to redesign the product and rewrite the instructions.  So I call this cheating.  And I'm not expecting a native English speaker nor a quick response.<br />-1 star.  I can't think of any use for the hard, spikey ball that was enclosed.  They don't seem to know of one either.<br /><br />So I'm left minus several stars, as in 5 - 9 = -4.  But I may keep it because:  it's a nuisance to send it back; I can possibly use it while I'm walking even if I can't sit down;  it may help my shoulders a little; and, most of the others on Amazon have a similar design so not much help there.<br />But whatever you do, don't believe the picture of the little old lady who is straightened up from a terrible kyphosis of the spine just by using this.  Wow -they do photoshop very well!
