    DO NOT WASTE MONEY BUYING THIS
  

*by J***E on Reviewed in the United States on April 23, 2019*

Do not buy this product.  I bought this 256GB USB after reading the the good reviews given here. Product looks good and solid. But no quality. You get what you paid for.  Very slow transfer rate.  This took  approximately 3 hours to copy 100 GB of data (audio).  And it did-not  even copy all files (this are simply mp3 files)  It says some of the files are saved as hidden.  But nothing was saved. as hidden. And getting error messages some other MP3 files.  Never happened this before, while using other USBs.  Total waste of time and money.  Returning it today and getting a branded USB that I can trust.

    Solid and rugged.
  

*by P***L on Reviewed in the United States on April 25, 2019*

Seems very solid construction.Has no led activity light but that's fine. I didn't expect it to have one.Mine came formatted exFat. Standard now for thumb drives. Plays mp4 videos just fine. Hope it holds up. Just wanted a rugged storage for videos and music for my new Atoto android car head unit which has both usb and sd card slots.

    bad purchase experience
  

*by E***R on Reviewed in the United States on May 15, 2019*

I purchased this usb to backup my laptop that is old and needs replacing.  I thought this item would be great to backup files before it goes out on me.  Very slow transferring files, checked usb, partial files, corrupt files or no files transferred. I thought it was user error before reading these reviews.  AND, at least twice it made a strange swishing sound ??????  weird!!
