*by J***L on Reviewed in the United States 🇺🇸 on December 15, 2022*

I love the fact that this product is well built, and has just the features i am looking for with none of the unnecessary additions that might make it fragile or flaky.  It just reads your cards.  Perfectly every time.  I have 6 of these stashed in different places so that when i take pictures or video, i always have a quick way of getting my photos and videos.

    Works Great!
  

*by A***R on Reviewed in the United States 🇺🇸 on December 11, 2022*

My laptop stopped reading my SD cards and this card reader bought it back to life without having to do anything other than plugging it into a USB slot. There was no lag time and my old Lenovo 2012 G510 laptop running Windows 10 recognized it immediately.
