Energy Star Holiday Time 20 LED G40 G-40 Red-Green-Blue-White Bulb Color Changing Lights w/Wireless Remote Control

The lights are great - durable, not as heavy as the old bulbs, etc. However I have had a problem each of the last 2 years. I connect 10 sets of lights across the front of the house. But finding a spot where I can stand, press the color change button on the remote, and have ALL of the lights change has been essentially impossible. So we live with the green (that is what comes on when powered up), because they all start that way - but when I try to change to another color or racing multicolor , some strings change and some don't - making it look stupid.It would be MUCH better if all of the other receives could be disabled and only have the first string be able to change all of the others to stay synchronized.
