🔒 Lindy USB Port Blocker - Pack of 10 - Blue 40462: Secure Your Data and Prevent Unauthorized Access Review

I have a lot of computers in my lab. I don't want users to bring flash drives and possibly infect computers with viruses. I bought these with a set of keys and they are great!

Good product. As described and I feel a lot better when someone tries to plug in a USB stick loaded with malware. They're also needed for USB-C, HDMI, and Lightning connectors.

Works well. I bought these to protect open ports on my family's laptops. They prevent dirt and other materials from getting into the USB ports when they are not in use.

USB port blocker. It blocks USB ports. I only gave it three stars because it's very easy to get around with a regular paperclip and the removal tool itself is overpriced. There are better options, but this will do for most.

If you have the time and inclination, you can pull them out - they're not infallible, but they're used to block accidental or relatively safe USB access. You can mix and match, just make sure you have the right key to remove them or you're in for an escalation day.

We use this as an extra layer for PCI compliance. This prevents the USB stick or mobile phone from being connected. We have 2 computers and sometimes users don't understand the difference and tend to connect their devices to the wrong computer. By installing on the front USB ports, they no longer connect their devices to the wrong computer. It's a retention device and with enough force you can pull it out with a tool.

I bought this with a blue key only to realize I had overlooked that the color of the key only works with the port blocker of the same colour. I missed that, but since you can remove them with tweezers (port blocker, not port blocker), it seems nonsensical. Now I have to buy another key. Maybe that's the point. Love the product but would love it even more if it wasn't so easy to remove with tweezers. It prevents people from connecting their phones to a PC, but I don't know anything about privacy
