Four Spray Humidifier Module Type-C USB Mini Humidifier DIY Kits Mist Maker and Driver Board 4 Fogger Atomization Film Atomizer Sheet Oscillating

I got these as well as a humidity controller and am using them to maintain the humidity in my humidor. My cigars are dry and they crack when I cut them. I have 4 large jars of the humidor gel, but the cigars still dried out. These small humidors are sitting in distilled water and sending out a fine mist that is perfect for actively bringing my humidity back up to where it needs to be. My only complaints with this device are that there were no instructions, and that it isn't ideal for my use as when the controller shuts it down, it will require me to open the door and push the button in order for it to come back on.

Let’s start with the price, at about ten bucks it’s not horrible, but not great either. You can get a selection of the same kits off that one A.Express place for just a couple of dollars. Of course here you get easier returns and better customer support I’m sure.The first thing I noticed was there are no instructions included of any kind. Just a plastic pouch with the parts in it. If you have never used these types of piezo devices you may have no idea which direction is which and how to use them. The indented or negative (dish) side is what will face up and pump out the mist. The positive bump side faces down. I also suggest pre-wetting the siphon/sponge material to get the fastest response or you may sit there waiting quite some time for it to actually wick up enough to start working.As for function, they do work pretty well and the yellow snap covers are decent. The left button is on/off and the right button is the mode select/cycle. The modes are: solid on, which can be one, two, three, or all four; auto-cycle/step through from left to right with one second between module activation in a snake-like where it counts up from one to four and then down four to one then off.It’s a bummer it does not come with an enclosure, but for the price and that it’s a ‘DIY’ type kit I suspect this is targeting people who intended to figure out their own enclosures anyhow. It does what it does and if that’s what you want, then get it for a few bucks.

Fun and entertaining for children! My kids love this. Read in reviews that there were no directions, correct, but the only hint needed is the top and bottom of the disks… the concave side it the top, the side will lots of holes. On button and a pattern button. Very easy to figure out.

This device is slated to be part of Husband's parts stash for his electronic projects/experiments to learn more about humidity as it relates to snake habitats. He reports that preliminary testing has proven positive. The components seem well made and everything performed as advertised.

This product includes a chip board with USB-C 5V in, and 4 output ports, suited for each of the 4 atomizer outputs, which come with sponges and connective housing for the atomizers and the sponges. It would have been nice if the product included an enclosure for the chip board, but perhaps that sort of thing can be found online. The product works well, upon initial examination, and I plan to use it for aeroponics, in applying water to the roots of plants, inside of some kind of setup; I've still to figure that part out. Thanks for putting this item up on Amazon!

while i don't have a direct application yet for this mister, i did test and confirm it is working as described. Good quality and shipped quick.
