Review: Great little humidifier for storing and incubating my hatching eggs! - I love these! They are a great size, and so versatile, and easy to use. They were easy to assemble, and set up for my purposes only took about a half hour to figure out. I set them up yesterday, and so far, they are working great. I used one in my table top chicken egg incubator to keep the humidity where I want it. Most of them do not have humidity control, only monitoring. They use water storage of different size surface areas in the bottom of the incubator and rely on evaporation and surface area of the water to keep the humidity in the right range. But this can be difficult sometimes with people living in different climates. I am keeping the smallest water section full and stuck the wick down through the grid on the bottom into the water. I have this connected to a humidity controller and it's working great! I used another one in my little wine refrigerator where I store hatching eggs until they are ready to start incubating. It's good to keep them at 75% humidity. I don't have a controller for that one yet, so I am periodically turning it on for a minute. I have a humidity monitor with a probe that goes inside so I know what the humidity level is. I have a couple of Swedish cloths/sponges laying flat on the bottom and saturated them with water. The wick is sitting on top of one of those. That is working well so far too!
Review: Quality Parts, Good Design, and excellent wicking setup - I'm using this to atomize neurotoxin for a Portal/GLaDOS themed project. Some things I really like about it: * The piezoelectric disc wires connect to the circuit board via a very reliable IDC connector. On other brands I've purchased, the wires are soldered directly to the PCB and break off easily. * The wick is VERY effective at providing the disc just the right about of liquid. * The PCB has through-hole pads on it for connecting your own power, and SMT pads to solder-jumper the switch to be permanently on. This makes it easy to control from a microcontroller. * The PCB has mounting holes to easily attach it to a project. Really the only downside I've encountered so far is that the LED is blue and very bright. I wish it could be easily disabled. Power usage at full steam is 250mA @ 5V. For others who might get it: When assembling this, the white ceramic ring side of the disc goes up (opposite the tube assembly). Also, before clipping the two halves together, make sure the wires are going through the correct side. Only one side has a gap for them.

## Features

- High-frequency oscillation, micrometer aperture, large atomization amount, fine mist particles, high spray rate
- The atomizing piece needs to be used together with the circuit board with the same frequency to achieve the ideal spray amount
- The left and right welding points of the switch can be welded together to realize power on, i.e. spray, without the need to control the switch
- There are two wires, the red wire is positive and the black wire is negative. The wire is 80mm long and there are terminal blocks at the end of the wire
- There is waterproof adhesive on the welding points of the wires to prevent circuit breakers, and a silver oxide layer on the surface of the atomizing sheet to protect the coating from oxidation
