Lindy USB Port Blocker - Pack of 4, Blue (40452)

Easy to use and remove, does the trick for port blocking. Make sure on reorder that you get the proper color inserts to go with the included tool, though. Note that these are in no way "high security" locks, but will prevent casual (and up to semi-determined) access to USB ports. Tool is pretty cool.

Got this to keep the Kia Boys from stealing my car with the TikTok hack. Goes in easy. Doesn't come out without the included key. I tried to pry it out with a knife blade but could not.

Very good quality and also fast delivery.

I think this is a great product, but the description refers to them as “locks”, but the item does not actually lock into the USB port. We have a problem with users trying to charge their phones through any USB port on any device they can find. This would not be a problem if they wound not end up somehow breaking them in the process. While this item does not physically lock into the USB port and can easily be removed with a small screw driver, I am giving this product 4 stars because it usually fits flush if not deep into the port and prevents the vast majority of users from trying to remove it...

In this day and age computer security can be a problem these little devices work wonders. It doesn't take much to put them in but, without the handy dandy removal tool you almost have to wreck the USB port to get it out. Well worth the money spent to secure office computers.

If you have USB ports that you need to control access to, this is your answer. As another reviewer stated, this are only blockers, and if someone is determined enough these can be removed with a couple of small screwdrivers. But for the other 99.99% of the population it keeps them out. With cyber security and guarding of digital accesses concerns on the rise, these little jewels fit the bill.

Si era lo indicado.

Had my doubts about this but as soon as I got it and used it on blocking my iMac usb ports it worked like a charm. Highly recommended this for Apple Pcs.
