There isn't much more to be said.. First, there is the Sandisk name, Sandisk quality and Sandisk speed. The packaging was done well and shipping was not an issue.  As a professional for both video and photography, I've never had a Sandisk product fail me.  This unit was purchased specifically for my GoPro Hero 3+ Black, but could just as easily work in my Canon 5D mk III (with an adapter) in one of its dual slots.
