[On the product]
Contrary to what have said the only comment so far on existing Amazon (1 Comment star of a person who has clearly not read the product description), this case perfectly accommodates the USB Disk for which it is intended (ie, the range My Passport). She hugs the disk and has a small site, very useful for storing the cable there.
While neoprene, it is however too thin to protect the drive when dropped.
[Verdict]
I highly recommend this nice cover for those who want to transport their USB hard drive WD My Passport.
