I argee with you guys,you do have a point. I need it because I go on vacation and its easier for the person whos watching the frogs to just turn it on and forget about. I was leaning towards the exo terra monsoon because its affordable and its a timer and etc. Like what cheri said. I also have 2 terraiums the mist so it would be easy for me cause I am not at home in the day time. Thanks for helping me out
