Mist cooing systems

[Mark_1984]

I've just seen Stuart's latest video where is shows a KoolMist cooling system.
This seems like a good idea, better than my current practice of spraying WD40 or WD40 cutting cutting fluid from a can.

Does anybody have any experience with these and can offer any advice before I splash out? KoolMist don't seem to be easily available in the, but Chinese imitations are quite cheap. Are the cheap copies any good?

Thanks in advance.

I used water filter canisters and modified them
The Coolant nozzles I got from Aliexpress
There are two separate systems one for the lathe and on for the mill, there is a 12 volt solenoid in the air lines connected to a switch to turn them on or off
They only require about 5 to 7 pound pressure in the canister
