Handy little adapter, as it has a lot of functions in 1 device.
I can connect my old monitor via VGA from my laptop for work, so I can work in dual screen mode, then when I am home I can plug my laptop into my projector via HDMI.
I also have extra usb ports on the adapter for my laptop, handy when there are only 2 usb connections and I need to connect more devices.
I also have the ability to slot my sd card from my camera into this device, so I am able to transfer my pictures and videos onto my laptop.
