30 Pcs Silicone USB Port Cover Anti Dust Protector for Female End Black

Good and useful. But Pricey

USB A - Dust cover - brilliant little item. Is your kitchen fitted with 13amp sockets with USB sockets ? These little plugs will protect the USB port from dust, spray and steam..... Also perfect for laptops, PC's, USB hubs or chargers to keep the port clean from debris, dust, fluff, pet hair or moisture. Good design with a slight raised edge on one side to assist with removing the plug, just get your nail and push.... easy.

Enfin des capuchons de protection qui restent bien en place ! Utilisés sur des entrées USB de matériel hi-fi (ampli, lecteur Blu-ray et autres streamer) comme pour des ordinateurs (fixe et/ou portable), ces capuchons sont faciles à installer comme à retirer.

Good product for the price that does what it's sold to do, go into USB-A ports and cover the opening. I don't know about "water resistance" for this thing but I would not trust it with submerging any product with this thing into water and expecting the cover to block out water. I bought this thing to block out dust and it does so very good. However yea that seal strength wont' keep out water. Don't push it in too far. If you do It will become very hard to take out. That little nub on the top of the product helps juuuuuuussssssst a little bit but don't rely on it too much or else it'll break off. You're better off just pushing the product in 50-80% the way into a USB port so that way a least a little bit will stick out and will make it easy to remove. Works like a charm for me.

There's not much to say. They fit, they do the job, and it keeps dust out of USB ports. Wanted this for some older business machines being repurposed to HTPC's as they had abnormal amounts of USB ports. They do the trick and don't fall out. 5-stars for doing what they are intended to do.

I plug all empty ports with these. Now when used there's no build up of dirt in the port.
