Will save much money & time later by preventing further corrosion in my switch.

good

Exactly whats needed for keeping spare switch ports clean :)

Recommended, I use it for my home router, laptop, wireless camera.

Worked great, product was exactly as described.

They do what you would expect. I mounted my router on the way which now means the network jacks are point up allowing dust to settle in them, and possibly inside the router. Plugged up the jacks not in use. Also makes it look a little cleaner than seeing open network jacks. Not sure if they really help in keeping the inside of the router dust free, but they do look nice.

Bought 30, all fit perfectly. Would recommend them.

Perfect Ethernet port covers. Fit snug and stay in! Simple as that!

These represent an excellent solution for a very small problem. The rubber dust covers fit snugly into ethernet ports and Im quite comfortable they serve their purpose well (in this case protecting a switch installed into my garage workshop serving networked devices and some ethernet jacks connected through my attic). A tab allows for easy removal.
