iExcell 25 Pcs Black Ethernet Hub Port RJ45 Anti Dust Cover Cap Protector Plug

Good quality

Only 4 stars as I havent had time to run these through their paces, but they seem like they will fit the bill. My priority of use was to plug up an empty microphone port on the back of an HF radio (mic is plugged into the remote head port not the radio itself). It seems like the dust bunnys always attack the back of your equipment, shyness I suppose ;) The first one I installed is a little ornery getting inserted, but once in, seems tight and flush with the surrounding port which is a good thing. Id say these are perfect for protecting the ports you seldom; maybe never use. If you need something you will be accessing often, I would thing these would eventually loose their stopper ability if constantly inserted and removed. Great for Amateur radio operators with all the RJ45 jacks on everything these days. Would definitely recommend for anyone wanting to protect said jacks on their pack-able radios at least. Now to plug up all the unused ethernet ports on my PCs ;)

Nice to have a quality thingy to cover my rj45 plug on my laptop.

Gives an incredibly tight bond to the port, but I can see how this will probably require tweezers to pull free when the time comes to use the ports I sealed up. Ive left about a 1/8 of the top part of the cover sticking up above the surface so that in the future I can get my fingernails digging into that. The tiny tab on the front is simply there to mock you. So Im using these for semi-permament applications. Otherwise does exactly what the tin says and effective at that.

Seals the connection tight and holds in place very well.

Very useful for unused Ethernet cable outlets, easy to apply it on

Great

Did what i needed them to do. Simple as that.

Worked as expected.

Works as designed
