Pros Looks great. It's stylish, sleek and space saving
Cons Reliability issues. I've used it twice as a backup drive and on the third attempt to backup my laptop, I got a message the disk was unreadable.
Summary It was unrepairable on the disk utility tools. It has been carefully stored between backups so no hard treatment to make it suddenly unreadable, and it's been connected 3 times to my laptop so not a lot of use to generate a corruption somewhere. Very disappointed I wasted my money on it but glad I found out that it was now unusable before I needed to retrieve any backed up data from it.
