This product is easy to setup and comes with all the leads you might need to get it working. Just connect to the monitor output on your computer and then connect the video out to you T.V. It uses a USB lead for the power supply so there is no need to plug in a powwer adaptor.
The problem with the unit is the picture quality, which is poor. I didn't expect it to be perfect, but there is a big difference in quality between connecting the VGA lead directly into the TV, or via this unit into the composite video input. The whole picture looks out of focus, and there is little adjustment on the unit to correct it.
