Yes, they work quite well. They lack many of the features of the more expensive models though...no night mode...no feeding mode...ect... What you have is a powerstrip with a dial on it. Three of the outlets are regular outlets...on all the time. The other three are connected to the timer which is controlled by the dial. Two of the timed plugs alternate on/off. The third operates on a different frequency. The timer can be set from 20 sec to 3 min. For example, if A and B are alternating on a 20 second on/off cycle, C will cut on/off every 40 seconds. I have been using one for quite a while and have been pleased with it. Although I don't know the exchange rate, $153.00C seems a bit high. Might shop around some more.
