Four Spray Humidifier Module DC 5V DIY Humidifier Control Board Atomizer Drive Board Four Way Ultrasonic Drive Board

This has bad reviews but price was so cheap I took risk. It worked great. Wish it had sum instructions but cheap they gotta save money sum how. Now this review could change if it burns out right away. Using it (may need a few more) for vaporizing water methanol mix for car engine. Control board will be in water proof box. It'll only activate when turned on & gas peddle to floor. So just few seconds threw each shift . Don't think it'll have time to get hot or over used. But I do think I'll need a lot more to make enough mist fog. Has cool led lights . Happy to say it worked for me & I'll buy a few more. Thank you fellow humans.

This product made for a cool diy humidifier that worked great for a few days in my greenhouse, shortly died after. Questionable reliability with good performance

The media could not be loaded. Works great! Creates a lot of mist. Worked right of the box. Just plugged in and all four atomizers started working. You do need to position them just right to allow them enough water to generate the mist without submerging them.

As stated in other reviews, the circuit board does not work. With a 5V usb-c supply, the LEDs don’t power on, the switches don’t do anything, and of course the misters don’t work as a result. DO NOT BUY.

I originally got this to make some fog for a pet tank. When I realized how dangerous this vibrations would be, I abandoned the project.It works as advertised, but just make sure that no human or animal flesh can come anywhere near the vibrating discs. The vibrations that atomize water will not be kind to your flesh.

I tried several power supplies, no lights, no humidifying, no nothing. D.O.A.I may have just gotten a defective unit, but it doesn't work. I'm very familiar with electronics and work with similar types of units all the time, so I know how to test them. This one did not pass the test.
