BUSHIBU USB Cover Cap, 20 Pcs Black Clear Plastic USB A Male Anti-Dust Plug Cover

Fit is great, nice and snug

I ordered some of these because I put USB sticks in my pocket, where lint and sometimes even dirt tend to collect. I garden so I'm in the dirt at times. I've used these on a few different brands of sticks, USB cables and other USB plugs. They fit snug enough to stay on until pulled off but are lose enough you don't have to use a screwdriver or pair of pliers to get it off. I'd say it is just about right. I've yet to have one come off without me taking it off. The material it is made of is a bit sticky like so it helps keep it in place. These are really nice and does the job really well.

These work well if you've lost the cap to a flash drive, or have a lot of little small sized dongles like unifying receivers from logitech or bluetooth adapters or whatever. It is hard plastic, no flex to it at all, and they fit very, very snugly - almost too tight on a few drives, which makes it hard to remove some of them. It didn't fit one of my drives at all, but that's a special one off drive made by Asus for my motherboard, so that might be why.

These fit securely, and are easy to put on and remove. Good price, too.

Excellent, just what I needed! Plenty of covers now! Yey

Fits well and helps protect the USB opening from damage

These flash drive caps have been great. After reading many reviews on the product, the most common complaint seems to be that they are very tight and can be hard to remove once put on a flash drive. After testing this, I can confirm this to be true at first. However, after leaving the cap on my flash drive for a day or two, I noticed that it was easier to remove than when I first put it on. Don't misread that, they were still plenty snug, but now I didn't need to yank at it for a whole minute to remove it. So don't be worried about all these reviews about these caps being super tight. Just put one on your flash drive and let it stretch out a little for maybe a night or two. After that they should be much better. Remember that these caps are a solid piece of plastic and so for the manufacturer to make them so that they can both stay firmly on a flash drive when applied and also be able to be removed fairly easily, a cap has very little tolerance for how tight/loose it can be made. I feel these have nailed it with being plenty snug and just loose enough that they can be removed easily with just a little breaking in.

Fits 50% of the way on USB connection. Tried putting one all the way flush, had to cut it off with an exacto-knife. Tried heating them up, seemed to fit snug but after 24hrs, they were still to tight to remove by hand when placed fully on connection. Tried all 20 on 3 different USB connection cables and drive. All fit about the same. Noticed also some of the corners scraping into the edges/corners of cap. They work but not what I expected. See picture, 32gb usb 3.0 drive with production date of 2017. UPDATE: I tried it a few out on older USB devices, one being a Microsoft corded USB mouse probably from early 2000's and a USB 2.0 8gb flashdrive (has to be older than 5 years). After a few times exercising the cap on, it was able to fit flush on the USB adapters. Tried it again on the USB 3.0 Samsung drive, still only fits to about 50%.

Pensé que por el precio serían frágiles o no servirían, pero si funcionan muy bien
