USB Port Caps, Silicone Anti Dust Cover Port Protection Plug for USB Type-C, 3.5mm Headphone, USB HDMI Port Total 20pcs

Plugged all of the unused ports on my motherboard and front I/O and even plugged the USB C port on my phone. They fit the ports perfectly and do exactly as described. Nothing will get in the ports. For my phone, I never use the USB C port thanks to wireless charging so I put a plug in there as well and it works great. No dust will get in there and if i do need access to the port, removing the plug is quick and easy.

Love these things! I purchased a PC tower with completely uncovered USB and AUX ports sitting at the very top of the case. IDK why this is becoming a standard, but it feels like you're setting yourself up for failure by inviting dust into your ports like that. I appreciate how this kit has a variety of covers, along with how easy it is to install and remove (removing them was the biggest worry of mine). I also greatly appreciate how these come with a small plastic snap case. I can easily just store the extras in the case and put them away for later!

They do what I want, keep dirt out of my USB plugs and receptacles.

Just this week I had a potential damage that could have been very bad on my PC. I was having a bad day Tuesday morning. Spilled my coffee at the pot causing sticky cream all over the counter. Then when I sat down at the PC, my arm hit the same coffee mug, that was almost empty, spilling some coffee on top of my PC. Some of the coffee got into the cracks of the door opening, and into the Audio/Mic input and the USB opening. WOW!. Lucky it wasn't alot. but it doesn't take alot either to short everything out. Poof over a thousand dollars ruin over a dollar cup of coffee. Being that my plugs are on top of my PC, is what makes this so important to plug and seal this area. Hats off to the shipper for getting these fast without fast shipment price. These plugs fit snug and is what is needed to CYA in the near future.

I needed covers for the ports on top of my new desktop PC (Fractal Define XL case) to prevent dust from getting in over time. These caps work very well, and they included the ones that I needed (USB-A, USB-C and 3.5 mm Audio). I also used the HDMI covers for the unused ports on the motherboard and GPU, although these ports are horizontal and therefore less affected by dust. The USB-A female caps also come in handy for USB sticks. Good product and works well. If you need caps for other special ports like e-SATA, RJ45, SD Card slots etc., there are other vendors who offer those.
