Micro SD Card Reader USB 3.0, Aluminum USB 3.0 Portable Memory Card Reader Adapter for PC

I love this adapter. I love that the micro SD card fits into the plug end, making it discreet. The adapter is a little tight for the card and removing it requires care, but the benefits of this design far outweigh the care needed, IMO. It does get warm, but that's to be expected when writing to the card. It supports 100+ mbps speeds. I was so pleased with this product, I bought a second one.

Has functioned perfectly with multiple SD cards. Nice sturdy construction. Very small and easy to mislay.. The metal surface is easy to write on to identify the function of the device. The mini SD cards are reasonably easy to remove.

These work great I have like 4 or 5 now but they get really hot during prolonged read/writes not to the point of burning your skin but hot enough that of you bump it you immediately know it's too hot but for my uses that doesn't really matter as long as it doesn't kill the SD cards and I've have them in daily use with a few cheap sp u3 v2 512 SD cards and they have been just fine for the last few months

The item is very nice and easy to carry around. You aren't able to attach it to your keychain, but you can easily throw it into your pocket or into your backpack. And feels nice and sturdy, not cheap at all. It is very easy to change out the microSD cards as well! I'm glad I bought this!

I used a similar micro sd card reader from sandisk in my tesla. the sandisk one was good but whenever something touches the card reader it stopped working and i had to push it inside again. this was terrible loose connection from sandisk. hence i decided to buy this one where the sd card is inside and there was no way to touch the sd card by hand or by cable etc. the only worry i had was if the card reader will cause any decrease in speed in comparison to sandisk reader but it did not. so i can say that the speed will be based on the micro sd card and this card reader will not reduce the speed if using it in the correct usb ports. this is the perfect one to be used for tesla usb music or dash cam or sentry cam.

It works with computer, but when I tried to use it with my Tesla model Y, it cannot be detected.

Paired with a good micro-SD card, this is super fast on both read and write. Gets a bit hot but nothing outrageous.

The device itself seems very intuitive, and it works like a charm. Trouble is, the casing gets hot enough to cause burns. I'm surprised it didn't fry my SD card, before I was able to pull it from the computer. Too bad too, since the design is really nice. Perhaps it should be sold with a heat sink or something.
