You're right. Some may think it's consumer's confusion, while others may argue it's deceiving advertising. Any consumer with a basic knonwledge about remote controls can easily fall for advertising that says "Can use Narrow Band width RF or IR to control all devices.". Even if they want to control some RF ceiling fan altogether with their A/V system, right? I know I would.

I just wish companies could be clear about their product advertising, to at least say something like "... for RF devices, it requires aditional such and such..."
