These timers are great. Easy to program (once you get the hang of it) and gives you lots of options. I love that they give you two ground jacks that you can program separately. My wife uses them for the plants she has in her terrarium. One outlet controls the lights 12 hours a day, and the other turns on the fan for 15 minutes every 4 hours. Great that everything is automated. We ended up ordering two more to put in our basement as it's getting colder now and she's bringing her plants inside. Highly recommended.
