Query: It works...what's not to like?

I bought two. One for the back of the house Christmas lights and one for the front Christmas lights. Plugged them in, plugged in the lights and touched one of the remotes while inside the house. Since both of the Skylink units are on the same channel (A) both of the strings of lights went on.....front and back. This works for me.If you just want one of the sets of lights to go on you need to get real close to one of the units and quickly toggle the remote and maybe just that string of lights will work. So, if you wanted one Skylink to turn on the coffee pot and another Skylink to turn on the lights in a room two WS-100/WS-100Ns would not be what you want. You should look for a two channel unit.
