Works great with a type C phone and a mac.

I was concerned over whether my phone's OTG implementation was compatible, it worked perfectly first time.

The short cable takes the strain off the phone's USB C connector.

If you're using this for a memory card for a camera, simply use your favorite file management app and either copy or move your pictures to where you want on your phone.

I use this to quickly and painlessly move pictures from my wildlife cameras to my phone. It is easy to back up files from the phone's internal or external memory as well if you're restricted in bandwidth, or prefer a local backup.
