Two very hopeful products have failed the practical portion of the test.
Mind you, the drives themselves are fine (they’re both 64GB USB 3 drives with “On-the-go” capability so they can be directly connected to a phone or tablet). But the mechanisms for hanging them from my keychain failed.
The first try was the Samsung on the left. The grey thing in the middle is the cap for the micro-USB connector. Note the hole; I used that to loop a cord with a keychain ring on it onto the drive. Worked fine for a few months, until I realized the cord (just nylon, I think, nothing exotic) was cutting through the plastic.
The second was the PNY, which came with the braided metal hanging cable. The mess on the left end of that was a catch that could attach to a keychain loop. But it broke today (that’s the spare piece at bottom left).
I can’t afford to keep buying these things every month or two!
