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

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

These fit in the ports quite well, they were snug, but not hard to insert. A small tab provides for easy removal. I believe these are probably most useful for network equipment that is mounted vertically. Do be sure to clean any dust from the port before insertion.

I have construction going on at work and decide to plug critical RJ45 ports on certain equipment in order to keep the dust out. These plugs fit nicely and the softness of the plug ensures they will not damage the port. I was concerned about heat but after monitoring my gear, I have not seen an increase in temp.

Plugs the holes well, keeps the dust out. Exactly what I was looking for in my garages mesh router AP. Ive got plenty extra which means I have no excuse not to use them indoors as well. I had no problems removing them, but I dont use the ports I plugged very often. If you were thinking of daily removal and replacement I would look for something with a bigger removal tag.

As advertised.

Easy rubber nubbings to plug your unused ethernet ports to prevent dust from screwing them up.

I liked them, but depending on the design of your device, it might fit or it might not. For example, on my mac Mini it doesnt fit well, so part of it ends up sticking out. But it does fit precisely on other devices like my Raspberry Pi 2 and 3B+.

They fit perfectly and are well made. Im very happy with my purchase.

Fit perfectly in Ethernet ports.

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 ;)
