Review on Upgrade 4L Reptile Humidifier - REPTI ZOO Large Reptile Mister Tank Terrarium Fogger for Reptiles, Amphibians, Herps, and Vivariums by Amy Lindsey

Generates a dense fog, has a top-fill function, very quiet. I bought this to replace a $45 bottom fill fog that started leaking unless it was on a PERFECTLY flat surface. For humidifying the terrarium. This unit worked BEAUTIFULLY for about two weeks and then inexplicably started leaking from the seam surrounding the bottom of the tank. Sometimes the leak is just above the control knob. I have to constantly wipe the puddle with towels and unplug the device every time because I'm afraid of electric shock. I am very disappointed and cannot recommend it. I specifically selected this product from similar ones because the ad said it was guaranteed to be leak free. I'd happily pay double to have a mist that doesn't actually leak.
