USB SD Card Reader for PC, 3 Packs Micro SD Card to USB Adapter, Card Reader for Camera Memory Card Reader, Wansurs Card Reader for Laptop (3 Pack USB2.0)

Used it for, flashing switch worked great

Bon produit fonctionne très bien

This is a tidy little card reader, and it worked like a champ when my larger, fancier, far more expensive card reader seemed not to recognize the SD card from my camera. Whew! This is definitely a five-star value, and - at the price - a winner. It's fast. It's easy to use. The light on it confirms that it's working, even with a tired Windows 10 laptop, so its compatibility is impressive, as well.

O produto chegou bem embalado e no prazo previsto. Já consegui utilizar com 2 cartões de memória, e funcionou perfeitamente, inclusive na velocidade USB 3.0. Recomendo!

For the price, five stars. It works, and it is cheap. What are you getting? A slow card reader. Plain and simple. Below are hdparm tests using the same microSD card for both runs. The only variable changed was the adapter. hdparm tests using the same micro sd card for both tests, only changing out the adapter: ``` user@dev:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:0029 Intel Corp.
