Review: They have a tight fit, but work as expected. - Met my expectations. Would do business again.
Review: Hak5 Malicious Cable Detector is a False Positive - Some of the negative reviews here are user related, but there's one I'd like to address and that is the claim that this does not block data because Hak5 Malicious Cable Detector detected it as malicious. That is a false positive from Hak5. You can do the research and see where those false positives occur and why. I’m not being critical of the Hak5 Malicious Cable Detector. The claim made that it doesn't block data because of that false positive is incorrect. I have tested this on Linux as well and it does block data. I tested all four pieces and they all operate appropriately. I cannot comment on longevity.

### ⭐⭐⭐⭐⭐ They have a tight fit, but work as expected.

### ⭐⭐⭐⭐ Works as described, disables and kind of data connection.
*by M***K on June 19, 2023*

Well, these definitely work as advertised. After a number of tests, data is completely disabled. This will affect the charging speed of a number of devices, as their quick-charge protocols cannot be detected, but that's an expected tradeoff when securely connecting to public power supplies. The build quality is decent, though the only minor issue is that the USB A plug does fit a little snug and requires a tiny bit more force to insert / remove. Still, great little data blocker plugs for the price.
