It an odd little system but it does work
I was not expecting these little misters to work so was pleasantly surprised at how well they do.  They are a bit fragile so when you fill the chamber you need to screw the two pieces together carefully.  They do put out a surprising amount of mist and I discovered that they work really well at helping to keep my 24 year old cat cool on hot days.  They also help me when my sinuses are acting up.  I don't think they will last for very long but so far they have worked well for the last 5 months.
