I would advise against that. I bought this one first for my cham, and it did almost nothing for me. Humidity wouldn't get high enough, cage would leak and drip everywhere. Eventually I got fed up with it and bought a mistking.
Its longest duration is a minute, and the intervals areever either 12,6,3, or 1 hours apart. It did nothing for my humidity, and the intervals were too short for my cham to get anything to drink.
It also doesn't really mist, but "rains" as the name implies. You also have to fill the thing up every day, and it would occasionally run dry on some days.
Get a aquazamp or mistking. They're a little more pricey, but worth it. Digital timer allows you to set whatever schedule you could want, and the use of a 5 gallon bucket means you only have to refill every 1-2 weeks or so.
