As people have said above, it simply doesn't work! I tried it with iPad3 and iPad2. In both cases it was not supported. The trouble and cost to the buyer of returning the product means that most people will just throw it in the trash and not bother with a refund just like me - and I am sure the seller knows this. Buyer beware!
It is possible to project information to a TV using the HDMI port. However... don't expect a full size display. If you are happy showing videos that uses less than half the screen area of the TV, you may be happy with this device. Note that there is no Apple port available when plugged in, so no charging or any other activity is possible while it is plugged in.
