Instructions not visible
Package instructions were covered with a sticker that was not removable and not readable.  I had to go back to the Amazon site to get correct instructions. The bottle does not say how much water to use.  It just said add 2 drops of test kit liquid to water. It should have said add 2 drops of test liquid to 2 teaspoons of water.  Results will be wrong if more water is used.  Also nowhere does it provide info re how much test liquid is in the bottle.  In fact the bottle only contains 10 mls. which is only about 2 teaspoons.  Poor Marketing.<br /> I won't be buying this again.
