I use it for sd card carriage. It holds two in it now.Also, the new case barely fits in the OEM carrying case. The bump on the back for the new kickstand sticks out and causes a poor fit in the case.
I am not sure if i am even going to use the new one since i do not really utilize the kickstand, but it is super cool of Dbrand to send a free replacement. They even included a little panel to increase airflow when using the kickstand and a USB-C extender
