On the website of Samsung is indeed that this dock will also be compatible with the SGS3. I can fully confirm! However, the docking station will only work with the version 4.1.2, which was released a few days ago. With my free branding S3 (V4.1.2) I've tested so far on TV HDMI, management of data on the computer and the connection with the mouse and keyboard. Everything works fine and this docking station is therefore also recommended for S3 users. One can also connect mass storage device (USB flash drives, external hard drives) and work with it. Charging function also works smoothly.
However, the device does not sit very stable in the docking station, but this is not a big drawback for me. Therefore, 5 stars!
Summary: + Charging function + HDMI port for monitors and TV sets + Mouse and keyboard function + Synchronization of data on PC ~ Price could be a bit cheaper - Device is not seated firmly in it (no limit)
