Dear John Jahsen M. Panes "JohnJahsen",
Thank you for taking the time to speak with me today and allowing me the opportunity to resolve the problem on your order! As promised, I am sending you the replacement case I personally tested with the Nano 7 and it is, indeed, very secure. I have also just emailed you with the new tracking number.
Again, I apologize for the inconvenience! If you have any questions, please feel free to contact me at 866.686.1800 Mon thru Fri 9:30AM - 5:30PM PST and I would be happy to further assist you.
