Reading the reviews it appears a lot of people didn't do their research, first you have people complaining it splashes, this it what these do, don't believe me take the lid off any humidifier you have while it's running. It's not a water fountain being falsely advertised or incorrectly advertised, it's an ultrasonic transducer or atomizer, it operates at a frequency that frees the water molecules from the water to create the mist you see. Also if splashing is such an issue, if people did their homework you'd know there is these little "gazebo" looking things you can get that you place them in to redirect the splash back downward, you can buy them separately or find one that comes as a kit. The other thing was people calling it an electrical hazard, well if your clumsy and don't know how to keep water away from your electrical components then yeah, sure, it's a hazard, normally common sense can prevail. I also cant help but think people are submerging them in too deep of water, this will cause it to not work, and even says so in the instructions, so if at first you added to much water and its not working, just remove a bit of water and try again. The product is well built, sturdy and when used accordingly is perfect for little DIY projects (plenty of youtube videos with great ideas) and the price is actually really good. The adaptor comes with a mid way connector, so you don't have to unplug it every time you need to fill the water back up or do whatever, you can just disconnect the midway connector and do what you have to do and then just snap it back in again which is really handy.
