## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great little BIG USB drive
  

*by J***L on Reviewed in the United States on December 18, 2018*

My Mac didn’t recognize initially until I formatted the drive on my PC. Now both formats recognize the drive and it‘s doing it’s job.  Looks nice, large capacity and great price!  Very satisfied.

### ⭐⭐⭐⭐⭐ 







  
  
    Holds a lot and is a great size
  

*by S***I on Reviewed in the United States on January 4, 2019*

I ordered this because it looked like it would hold a lot but was also compact. It was exactly what I was expecting. I do think I could have found something cheaper but this is worth the extra money to know you will get something that works as it says. Especially if you are in a pinch and need it ASAP. Overall I have been impressed! 😊

    Folders copied to the drive frequently lose their contents
  

*by T***Z on Reviewed in the United States on January 13, 2019*

Over and over again, I copied folders to this drive, only to have them reported as empty minutes later. This happened whether I copied the entire folder from my hard drive, or first created a folder on the jump drive and then copied only the files contained in a folder to that newly created folder. Despite being reported as empty by the file system (no files in the folder, folder contains 0 bytes), when I copied files into the empty folder, I was asked whether I wanted to replace the files already there (so there was inconsistent information about what files were in existence on the jump drive). When I asked for them to be replaced, in some cases, that resulted in an apparently successful copy, and in other cases, it did not. Even when a copy operation was apparently successful at first, the folder sometimes turned out to be reported as empty again minutes later. The long and short of this is that one cannot count on files copied to the drive being accessible after they are copied, which makes the drive worthless.
