We have had the Penguin humidifier for about a year and a half now. I had placed an order for one and a month later it hadn’t shipped so I canceled my order and got one in the store. I really love it. Its adorable in my daughter’s room and works really well. It has a turn knob so you can adjust the output very easily. I think on high it puts off a little too much because it was empty and the carpet was damp in the morning. It is easy to fill and clean, doesn’t use a filter and holds enough water for a night or two. My girlfriend has the elephant or frog I can’t remember which and is also really happy with it. She has had it for three years I believe. Go for it, they are adorable and if you don’t like it you can always return it!
