Waterproof 256GB USB Flash Drive Pen Drive Memory Stick for PC with Keychain

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.

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.

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!!

I like this flash drive. It stays attached to my lanyard. I cannot forget it.

I've barely used this thing and it's broken.

Very Sturdy usb stick

This was a great buy initially with its price, and the storage was great. However on the second day every time I inserted the usb drive into a windows laptop and mac pc, it would repeatedly ask my to format it, resulting in losing my files every time. I would look for something else.

Doesnt work, waste money. Im not sure its a flash drive. It does nothing and isnt recognized by the pc
