This is the Woods 50027 mini digital timer. It's a 2-prong unit, and has two "on" triggers and two "off" triggers per day. I (mistakenly) thought it had more on/off triggers per day, and do not need it. It costs $9 on Amazon.ca, so I'm asking for $5. Please Google for a more detailed description. I'll try to put a weblink to the Amazon advertisement. This unit is new. I have not used it.
