The glass vile broke while pushing the cap on, it is very thin glass and poor quality. This was only the 5th time I used it and lucky I didn't get cut.

This test is very simple to use. My only complaint is in the lower ranges it's very hard to read. Very light shades of color.

The Elos PO4 is the simplest test kit ever. Just add two drops of both solutions and your off. Only negative is shaking the vial for 5 minutes as the direction suggest. Other than that, this test kit rocks.

Big fan of Elos kits, so far big fan of Elos everything. Possibly one of the easiest kits to use, and the color cards are very accurate... Never used a hanna checker but honestly don't see the point, this tells me if I have any phosphate above 0.01, so good enough to maintain ULNS.

Your PO4 is reading zero BECAUSE the hair algae is feeding off it.
Not worth it By podcar on 3/3/2010

This test kit shows me having 0 phosphates, yet my aquarium is full of Hair Algae, so obviously phospahtes are there.
