Query: Poor range-Remote works once in awhile

This item is not worth it. I have the inside monitor on a fireplace sill and the outside monitor less than 10 feet away with line of sight through a window. It still cannot read the outside sensor except occasionally. Even with the sensor sitting next to the main unit, it only reads occasionally. Do not waste your money on this item.
