This unit worked well from 2016 to 2019 to transfer mirror images and then 4K videos from SD cards. It has been used little, maximum 1-2 times a month, MAXIMUM less than 100 times during the period of use. Then Windows stopped recognizing SD and MicroSD cards. Insert the card, the indicator flashes but does not appear in explorer. No obvious signs of internal damage, nothing happening. Maybe my expectations are too high, but Transcend has been around for a while, and yet I have a cheap, unbranded ("CCM Mobile") USB 2 card reader from 2008 that still works well (just slowly) with the I had to go back in the middle of a project when this device failed. I will try another brand starting with Anker AR200 - simply because their support is amazing.
