i have to say... the fogger/waterfall combonation from exoterra is wonderfull... i have one in my tokays tank and the humidity is about 70 without it on and then when i turn it on its about 90
its a very good purchase.. i recomend it to anyone that has a tropical lizard... i wouldnt recomend the fogger alone.. because it spits water EVERYWERE so.. if you are considering getting one or the other.. just buy both.. you will be happy
