Slightly misleading. I purchased the "regular" size as the description seems to state that it fits the Seagate Slim drives. That was kind of my fault for not reading the dimensions of both options. It does fit, but with so much extra room that it slides up and down, therefore the drive doesn't feel very secure. I ordered a second one upon seeing comparisons from other reviewers, this time choosing the "My Passport" version. It fits the Seagate Slim perfectly. I wanted to exchange the previous one I purchased, but Amazon just refunded me for it. (Thank you for being overly generous!)
Both products are great, and made very nicely, surprisingly. An inexpensive way to keep drives safe. However, don't make the same mistake I did. If you own the Seagate Slim, the "My Passport" version is the one that will fit, not the regular one. Check the image uploaded: top is regular size, bottom one is "My Passport" size.
