Questions about this item

How do I connect the reader to a USB-C phone and which slot do I use first?

Insert the USB-C plug into the phone's port, then insert an SD or microSD card into the matching slot; the reader works immediately with no driver installation.

Will the card slots wear out or need cleaning after heavy use?

The spring-loaded slots are rated for thousands of insertions; occasional compressed-air cleaning keeps contacts reliable.

What limits transfer speed when I copy large video files continuously?

The USB 3.0 interface caps the link at 5 Gbps, so sustained throughput cannot exceed that ceiling.
