WOW.... this worked perfectly with my 5 year old Sony TV. Amazingly it identified the TV as per the instructions in the packet. I'm more than happy as its great value for money and easy/convenient to use.
Well I use this for all my presentations and lecturing activities. Moment I connected to my laptop with Windows 7, it automatically installed it self and started working. You DON'T need to pin point the hand unit to the computer (like most of the other similar devices available). This works in any direction making it easy and convenient to use.
