Input: Great technology, but terrible case.  I lost the cap within two months of use because it doesn't fit tightly.  I contacted the manufacturer.  I was told in email they  would send me another cap for $20.  Yes, the small cap is $20!  I had it connected to my keychain and today it fell off because the connector broke. Two things wrong with it in a few months. I don't know if my issue is a one off or a quality control problem.  The cheap ones at Walmart have held up better.
