Let's talk about these 20-pack USB flash drives. First off, the price is unbeatable – at around $2 per drive, you're getting serious bang for your buck if you need multiple storage solutions.

The swivel design is actually pretty nifty. That 360° rotating metal cap feels surprisingly sturdy compared to cheap plastic thumb drives I've used before. No cracked caps after months of tossing them in my bag!

Where these really shine is for simple file transfers. I've been using them to move audiobooks for elderly relatives (perfect since you can color-code books) and they handle that job flawlessly. The keychain loop means I haven't lost a single one yet.

Now the not-so-great part: speed. These are USB 2.0, so expect old-school transfer rates (about 15MB/s read, 5MB/s write). Moving large files? Go make coffee – it'll take a while. And yes, a few users reported some duds in their batch.

The FAT32 format works with most devices out of the box, but that 4GB file limit can be annoying. You'll need to reformat for larger files.

Bottom line? For bulk storage of small files, school projects, or giveaways where speed isn't critical, these are fantastic value. Just don't expect premium performance at this price point.
