The adapter gives us installation hints on the top side:

Here are some other photos which show the bottom side of the adapter, the external SATA Data/Power ports and the internal SATA ports:

The drive gets fixed into the adapter with lateral screws and we can also see some yellow spacers on the laterals:

The plastic USB enclosure for the optical drive does have a small power LED on top:

On the lateral side we can see a sliding button, which allows us to lock the drive into place after it has been inserted:

On the bottom we have 4 small feet, a secondary sliding button for ejecting the drive after it has been inserted and a sticker with the product code name and power rating:

To fill the empty space where the optical drive used to be, we will also get a fake drive bay cover:

Of course, KingFast also supplies the necessary tools to perform the installation along with the USB cable for the optical drive enclosure:
