Originally I bought two to have one as a backup, but it worked better running them both. One stopped performing well so I bought another two a couple weeks ago and I'm still waiting. I went for the very cheapest price, so I'm sure it's on a boat from china and its gonna take a while. I will put links on the very next post. The diameter and height of the bowl you use is important because as you can see from the pictures below, it creates a stream of water that shoots up as well as fog. That stream can tend to splash out. In my case, a little bigger diameter bowl would be better. Height of the bowl is important as well because, too high and the fog will never pour out. Make sure bowl is not placed by anything they can climb up and fall into!!!!!!! That last picture was what I was working on and will finish this weekend. Since I had a little splash and since the fog uses up the water, you need a constant water source. Get a fitting or fashion something so that you can fill a bottle with water and strap it to something with the hole facing down and tube water tight. Cut tube to length and lead it to the water bowl just at the top. It will keep the actual bowl filled to the level you set the tube. I got the idea from dog bowls that have a two liter bottle you can screw into bowl that keep it filled. You can put the power supply on a timer and feel confident it will fog for how long you want it too. I bought my power supplies separately but I am also including a link with the both. Buy a few power supplies and more than a few diggers and you should be good. They come from china, so if you need them faster, pay a little more for the shipping. I wanted to get a raspberry pi setup to really keep an eye on things, but that's further down the road. A timer and these items should work just fine. I'm not sure if this is gonna post right away but as soon as it does ill use the app to upload the photos

I realize that two links in the second post are smoothed together, and the combo link is a fogger with pretty lights attached to it. Which might be cool, but I did not get those , mine were without lights
