"The Remote Controls effective range was great & I found I could easily use the Remote over the width of my house with a clear LOS (Line Of Sight) to the Infrared Receiver (This was a distance of about 30' overall). This range will probably be of more importance to those using such products in businesses (Perhaps for making presentations & such). It's fairly safe to say that the range won't be an issue for
anyone using this Remote in their home."
