Very good item, but I have had this for awhile ...
I have a short waist and cannot wear the wider back support belts.  Very good item, but I have had this for awhile and have a couple of comments 1) Over time, the velcro becomes loose. I had to stitch some wider velcro on it to make sure it does not come open.  2) The magnets do warm up quite a bit on bare skin!  Just be careful. I've had to remove the belt a few times or wear a camisole under it. (As the magnets use body heat to work, the camisole prevents it from heating up at all but still provides good back support.)
