Has anybody tried these from what I gather they use some sort of flavor syrup/pressure cannister.

Interesting stuff.

The saltwater filter seems pretty slow but the technology is interesting. I am not sure how it compares in price per volume of drinkable water with other options.

The regular filter claims it was “Used by soldiers to drink the floodwaters in New Orleans”; anybody with experience on that?

The description is not clear at TAD gear, the salt water unit either produces 1.8 liters OR 24gal if you calculate the expected filter life X's output. $100.00 for 24 gal of water
is not a bad trade, for 1.8 liters I'll pass. This also sounds like a one time use product,I wonder if the filter membrane expires AFTER 10 days from first use?
The portable osmotic membrane filter's have been around for
a few years trying to Find a market.
