X10 modules include: three 2pin appliance modules + two transceiver modules + two keychain remotes, a $140 value; you can verify prices at homeautomation or smarthome . I have used those for four years but these products have been known to last for thirty years.There is one of these units that might need replacement; I don't have necessary resources to find out which. Also one of the keychain remotes needs to have battery replaced. In spite of all this you are getting a great deal for $40! No returns accepted.
