The Ryobi 18V "Fogger" is great, but don't be fooled, it is not a fogger.
Unless you are looking to douse everything, you really should look at getting a proper fogger. Forever Fog machines create 10 micron size droplets and do a great job to keep things from getting wet.
In order to keep your electronics and computers safe, it is suggested you do not exceed 20 microns.
On top of being sold out, Ryobi Mister could cause you more problems and you realize.
