Review on JUANWE 5 Pack 32GB USB Flash Drive - Waterproof Metal Thumb Drive with Key Shape Design - Portable Memory Stick by Roger Gibbs

I've bought them before and they worked. However, this is no longer the case. Once initialized and loaded with a file or application, it becomes inaccessible no matter what machine I connected it to. The message states that the disc is unreadable. Once you remove the drive from your computer, you will NEVER, EVER, EVER access it.
