The SVNXINGTII 100Pcs Ethernet Dust Covers were a welcome addition to my tech setup by providing adequate protection for my network ports. Their straightforward design allows for quick and hassle-free installation, effectively safeguarding the RJ45 ports. They're easy to put in and remove. I don't have much more to say about these, aside from if you're looking to protect your ports from dust - I highly recommend them.

Fits well in a normal RJ45 port. I don't use these often, but it's nice to keep junk out of ports in an unideal environment. Now the unused ports in my shop won't get full of dust.

So first off, count how many you get. My box of "100" has 91 caps in it.The caps are soft rubber not hard plastic. I put in 24 and had no issues with them. They went right into the ports and fit well. I do wish they came in a better box. It's almost impossible to close once you open it the first time.Overall they do the job and I'd be very happy if I wasn't shorted 9 caps.

These will do the job as long they're inserted in a horizontal facing port. In ports facing down 45 degrees, they will come out fairly quickly when experiencing a bit of vibration. I have used similar products that do not have this issue.
