Didn't work for me
Pretty much useless to me.  A waste of money.  It's not just a bit bigger than the standard cuff, it's roughly three times as large, and clumsy and clunky.  As noted in another review, it's very hard to use by yourself.  When you try to pull it tight, it just slips around the arm to the wrong position.  My not being seven feet tall, the cuff is also too long and gets pushed down into the elbow, also the wrong position.  Most of the measurements end up in errors.<br /><br />Suggest saving your money unless you are a huge person or have someone to help you.
