IT'S FINALLY HERE!!! I'M FLUORIDE FREE!!!
Suck it Bill Gates, Klaus Schwab, my local water utility company, and all the other population control freaks!
Expect a review soon.
@xianc78 filter your rain bucket with it 
@xianc78 oh yeah these are commonplace in russia, they just work
@lina They should be common place in America too, but most people aren't awake to the fluoride scam.
Normally, I try to avoid purchasing anything from Amazon, but this is a rare exception since I can't find this elsewhere, it's an essential item, and I can't convince my family to install a full-blown filter, but at least my family won't scold me for drinking water out of the rain bucket anymore.
