Excellent range all over the house with RF signal vs IF.5.

The system has a greater range of volume than anyone will ever need.

The range covers my entire house and garage and is not obstructed by walls or doors

And know that the "range" is sometimes unpredictable

” they were uncomfortable and range wasn’t very good

UPDATE (December 2013): After nine months of use, everything works just as perfectly as it did on day one
