The ACCELL MHL to HDMI adapter comes in a clear plastic retail package with clear directions.
Check out my full ZDNet Mobile Gadgeteer post for details on using these adapters and embedded YouTube videos of both adapters.
The ACCELL MHL adapter measures 6 inches in length with a microUSB male end and a HDMI female end for connectivity.
Here you can see the female and male ends of the adapter cable.
There is a female microUSB port on the dongle piece that you plug in a power source for selected devices. Power was required for my HTC Flyer to work.
I connected my HTC Flyer to the MHL adapter for testing video output.
Here you can see the adapter cable is placed into the bottom microUSB port of the HTC Flyer.
This image shows the power cable plugged into the MHL adapter.
As you can see the HTC Flyer display is shown on the 37" TV. This is the display that appears when using the DLNA adapter, but you can view this and much more when using the MHL adapter.
This image shows that the full HTC Sense UI and Flyer display appears on the TV when connected via the MHL adapter.
HTC Watch media content can be viewed through the MHL adapter.
I enjoyed watching I Am Legend in full HD quality through my HTC Flyer and the MHL adapter.
There was no stuttering or slowdown at any time while watching fast action movies on the HTC Flyer.
The HTC Media Link retail box has sketches showing how the setup works.
HTC includes the charger and cables you need to get all setup and enjoy your media experience. The only thing you need to provide is an HTC supported phone.
The HTC Media Link main adapter is small with HDMI and microUSB ports on one end.
There is a small power switch on the HTC Media Link.
The HTC Media Link is just about the size of a few credit cards and is easily transportable.
