Had to pay for return box because it came in plastic , you owe me $4.50 to return it back to youI love it. So far it is working well and adding much needed moisture to the room. Plus it is an adorable addition to the bedside table. Kids love the cute little penguin puffing mist into the room.It arrived in good condition and swiftly after ordering.Thank you!I know what you're thinking "Aww how cute! And it works with my water bottle!" Don't buy this. Spend $20 on a REAL cool mist humidifier lol "Works up to 12 hours with one water bottle" if you can stop it from spewing all 15 oz of water out of the duck! I was soooo pissed. Only keeping it because daughter likes the duck design & sending it back would be a hassle.Leaked from the moment it was plugged in until the moment I put it back in the box & returned it to Amazon. It's like the water just funneled out the of the bottle and through the bottom of the duck, spilling all over the nightstand table and floor. Never did anything "ultrasonic" out of it's beak - it just ran straight out the bottom. Needs to be pulled out of inventory & redesigned ASAP, before someone electrocutes themselves with this thing.This little guy puts out way more mist than you would think from the size. I keep it in my office, and everyone has commented on how cute it is. It is pretty much silent, and adjusts to save water. It doesn't last twelve hours, but then I tend to run it on higher settings, and it does last a long time per small bottle. I thought it would be unstable, but it has outriggers that keep it firm and balanced.Leaks. Bought a different one, different company for my daughter. It worked great but was no longer available. This one leaked.This humidifier is easy to use and so convenient. I have it on my night stand and it gets the job done. The perfect amount of mist comes out and I don’t even have it completely turned up. Would definitely purchase again.Convenient and affordable product. I would highly recommend this if you do not like cleaning the larger humidifiers weekly.Bought this for my desk at work. Once it starts working, it does it well, until the water runs out, so that's the positive. The negative is every morning, this thing makes the loudest most annoying sound for about 10 minutes until it "warms up". Gently tapping it makes it go away for 3 before it "whirrs" up again. Coworkers find it annoying until that sound goes away, then it's pretty silent when in normal running operation. This would be much better if it had a fan to blow the mist out a further distance though, as sitting on the desk basically makes anything around it wet (papers, etc.). I work in a very dry office (10% humidity) and this bumps my desk to only 20-25% or so on a good day. Better than nothing, but would have hoped for more to save my dried out sinuses. Overall, a decent product if you want something small, easy to fill (just a regular water bottle works), and portable. You could bring it on trips, but with this sound that it makes on startup, I passed that up on my most recent trip. I don't want to hear a whirring in my hotel room in Vegas when I turn it on.It’s okay but makes very strange dying noisesThis is a very awesome little machine. Works good.The item leaked, spout was broken off so steam couldn’t come out. So was unusable.Its great for me as I work in remote work camps. The compact design is perfect for packing away for storage and it works well to alleviate the really dry air up north.
