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

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.

It fits really well in the USB ports, specifically the ones on my desktop and other things that have USB ports. However, it is REALLY difficult to remove the plugs from the laptop ports. You either need good nails or something sharp enough to remove it from the laptop ports. Other than that, the plugs works great for other ports.

The quality of these items is great. They are easy to remove and seem very durable. They are very functional, fit perfectly and will be great at keeping dust out of your electronics. These are a great value for the price.

These are great to have for any electronics that might be exposed to the elements or even the bottom of your backpack. But I have used better ones. These ones don't quite stay in as well and aren't quite as easy to pull out as another brand I've tried. But still pretty good.

Nice and soft, do their job well

I use these to cover up any USB port that isn't actively being used to prevent dust/dirt/debris getting into the port and possibly ruining it. Quality is top notch. Super easy to use They provide dust protection to keep your USB ports running smoothly. Super affordable. I use these on any computers or portable power stations with USB ports not actively being used (in my vehicles as well!)

A great product to purchase to cut down on dust getting into the USB (F) 2.0 and 3.0 ports especially if you have them on the top of your computer case. They fit in perfectly and are extremely easy to take out when you need to use them.

There's some wiggle room so they might fall out in the right situations. Alternatively, if you have something with a recessed usb port, you'll need tweezers or something to get it out. Big plus is how many there are for the price, would recomend.

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.

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.

Good and useful. But Pricey

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