For those using these as API replacements: plan to wash them at least twice between uses, I use them often and if you flush them and put them on a paper toilet over time it will remove some of the test chemicals rinsed out badly (usually blue) on towels. I recommend rinsing them well and then placing them upside down in a large shot glass with a paper towel at the bottom. Also, they work, but I can't say I would buy the same ones again. broke upon arrival which is not cool.
