Works ok. Build quality feels good. It's real metal, not painted plastic. BUT It's not USB3. The speed is only ~20MB/s. And the USB-C plug is a bit tight.
My first microSD card is inside of the memory reader. I sent a video that shows my second microSD card being inserted into the reader. I remove my second microSD card and then shake to the reader. You can hear my first microSD card still inside the reader. I have 4 pictures uploaded. The microSD slot is an empty space. My second microSD card can totally be inserted into the slot. Even when my first microSD card is still inside. Conclusion: The microSD slot is an empty space. Card reader is defective. Request #1: refund for the reader. Request #2: suggestion on how to extract my first microSD card from the reader. Green Leaf responded with 'can not see'. No response on my questions.
