Don't waste your money. Too small to fit Iphone 6 or Iphone 7.
This appears to be a well-built and durable piece of equipment, but larger phones such as the iphone 6s plus will not be able to be secured, as the strap is far too short. An old iphone 4s did fit and was able to be secured. It really needs a longer adjustable securing strap for many of the newer, larger phones available.
