10x Anti Dust Plugs for Smartphone, MacBook, Laptop | USB-C Dust Plug for Samsung Galaxy S8, S9, S10 | Silicone Dust Plug – Black

So far works well to keep dirt and hay out of my ports when working in a barnyard. It is a little annoying trying to take the little plug out of the charging port, then you have to not lose it while charging, and THEN trying to get that sucker back in! But again, I'm no longer having strands of hay get stuck inside the ports so I'm happy about that! I'm just concerned about losing the nubs when a port is in use, but I guess overall it's a cheap product and I could just buy new ones as needed.Would not recommend if you have animals in your home that could eat stuff off the floor. I could easily see a cat or whatnot being curious and swallowing the nubs when put aside while charging. They seem small enough to pass if it does happen, but something to consider none the less.

My challenge was I just bought a Samsung Galaxy S20 FE which does not have very many options for cases out on the market yet. The best case I decided to go with is great, however the one thing it lacked was a port protector for the USB-C charging port which I use very, very rarely b/c I primarily rely on wireless charging. So, I not only wanted to something that I could use to protect the port but would 1 - fit alongside the case and even preferably be flush or sunken into the case itself and 2 - be easily removable for when I do need to use the charging port, i.e. - when using the phone for navigation in the car and need it plugged in.These plugs satisfied both. It fits perfectly inside the cutout of the case for the port and does not protrude - thumbs up. And it's flexible/easy enough to get my finger in there to pull it out when I want to use the charging port. Problem solved.Side notes:- the plug seems to hold well enough in the port that I'm not worried about it falling out- Other than an accidental splash, I wouldn't count on this plug protecting the port from water. I only bring this up b/c it's listed in the rated features via the reviews, it wasn't even a consideration of mine. So, where it does, I guess, provide some water resistance since it covers the port - I wouldn't count on this keep water out if it were submerged or something of that nature. So, I'll give 3 out 5 stars for water resistance since it's better than nothing, but definitely not IP6 rated or anything of that nature.

These are dark grey or black in color. There is no aluminum cap to fall off. The color goes all the way through the plugs, unlike the plugs that are white plastic with a dark cap which easily falls off leaving the white plastic visible. My phone is a Samsung S21+. In dark grey color in a dark grey case. These plugs being silicone slide into place easily and don't fall out. They fit in the phone without interfering with the case and the color blends in so you can't really see it at all. It does not stuck out beyond the edge of the case so the phone still sits perfectly on its upright charging cradle. My phone does not have a headphone jack so I can't comment on those plugs,, but for the price for 10 USB plugs, I am very happy. I'm sure the silicone material enhances the water resistance of the USB port. I fell in a river a few years ago with my Samsung S8+ and the USB port was never the same afterwards. If I had one of these plugs in it I'm sure it would have fared much better.

Clean packaging! They are made of rubber and do feel pretty secure in my phone's USB C port.The reason I bought these is I am planning on no using wired charging anymore I had a Nokia 6.1 and a BLU G9 - both if which charge via USB C. However, after a year of usage of each, the port was "loose", for lack of a better term. The Nokia I would have to Jimmy and jam the wire around for it to make some kind of co tsct to charge. For my BLU, while I can get it to charge, it no longer gets picked up by my laptop (so I can't do file transfer).Now I don't don't if this all due to some inherent instability of USB C - but it happening twice now within a year of usage, IV decided it's a safer bet to wirelessly charge. I bought these port covers as a way to protect my newer phone, where the only time I'd ever plug the wire in now is to do data transfer as needed.

I only needed one, but I'm glad I bought a bag full. These are the perfect thing to keep sand out of your USB port. My phone is already waterproof, but I go to the beach a lot and FL has sand everywhere. This is just what you need to protect your port. Easy to insert and remove. But easy to lose if you are careless.

They seem very well made and I expect they'll do the job. Appears to be a quite firm rubber material. 3.5mm plug a bit hard to remove as the top/cap (part that doesn't insert) is also very small, so hard to get fingernails under them. I just did not appreciate how tiny these are, normally these connectors are at the end of a cable, with overmolds around them, making them appear both larger and impossible to lose. I expect I'll be loosing these quickly. I bought these primarily for the 3.5mm, to replace an audio jack cover on a connector on a boat. Will be very hard not to lose without some sort of tether - I guess I'll try to make one.

The charging port on my past two phones became caked with pocket lint. I recently purchased a Pixel 4a and wanted to keep the charging port clean. This dust plug fits perfectly. It is snug and has yet to fall out. It is easy to remove for charging the phone. I have a case on my phone and it is still easy to access. Same thing with the headphone plug; it fits tight and keeps junk out. There is a metal rod on the headphone jack. I guess it works as a tool to remove the sim tray. I have not tested this, but I do not see why it would not work. A few reviews mentioned the pin could fall out. To me, it is very secure and I am not worried about that happening. After a month, I am still on my first set of plugs; they hold up well. I would highly recommend this product. It is cheap and does its job.

Works great. I work in a very dirty shop, and these have helped my phone a lot. The headphone jack plug has a very tight seal and keeps everything out. The USB-C plug doesn't seal as tight, so some stuff gets in, but these keep it way cleaner than before. I used to have to blow my phone out with electronics duster every day, now it's maybe once every couple of weeks. Some of my coworkers even wanted a few since they work so well.

Exactly what is meant for.Good.
