As you can see there are NO connectors for the "required" batteries and even if you find a power cord "not supplied" all this thing does is run a motor with offset weights to shake it.Definition of Ultrasonic: "Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" sound in its physical properties, except that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz in healthy young adults."Not just shakey movey and make water jiggle from our of round motor.Cannot return it because shipping to China is more than the value of this piece of crap. Wait crap can be more useful.There is no way this was originally $149. I paid a $15 for it and it is very cheap and cheesy. It looks more like something you would have gotten at a dollar store for about five bucks.
