Disappointed - great idea, but not a well made product.  I purchased this in May 2015 and used it over a 4 day weekend while traveling.  Then I took it on vacation in June 2015 and by the 3rd day of my vacation the strap pulled out of the area where it was sewn.  Checked on a return, but Amazon says it is out of the return period and I can't find information to talk to the seller to see if they would like to stand behind their product.  Buyer beware, and if you do purchase it - keep a tight grip on it.
