I got the "ASUS New Nexus 7 FHD Official Travel Cover" from Amazon. Not worth it. I was hoping it would fit as well and be as sturdy as the OEM travel cover for the original Nexus 7 (2012). This new cover is flimsier and the fit is surprisingly loose. It definitely does not have magnetic wake/sleep functionality when you open the cover (in fairness, the OEM travel cover for the 2012 Nexus 7 didn't either).
I'm the first guy to put OEM cases or covers on my devices, but pass on this one. It really kills the premium feel of the new Nexus 7. I'm holding off on another case and using an old Kindle Timbuk2 sleeve until Google or Asus make a better case available (if ever).
