The only negative thing is that it is very tight. It is made of relatively hard plastic and not soft silicone like other dust covers, resulting in needing some force to put it in and take it out. They may soften with use, but they are hard to the point where I wondered if they would damage the port in my attempt to put them on and take them off

By making everything wireless now, and with wireless charging, there is no longer a need for the type c port to be exposed. It closes well and is not exposed to dust and moisture.

It applies very well and does not come off from its position. It effectively protects against dust, lint, and moisture. The only issue is that once you remove it to charge the device, you need to be careful where you place it so it doesn't get lost.

It does its job perfectly. I put my phone in the side pocket of my pants all day. The result was that at some point the USB plug couldn't fit in any way. After spending an hour carefully cleaning the area with a pin from the debris, I bought these caps and problem solved. Simply nice and great.
