Worked well
Used as for generating SO2 gas to study a chemical reaction. Much cheaper than buying SO2 from laboratory chemical suppliers. Product was good price and arrived quickly. Will buy again if/when I run out.

It has been working pretty much as expected; I am using it for gold precipitation. Thanks Molly's!
