    Not used for the moment, the 6 reagents provided with the photometer have been sufficient for now. (Translated review)

    It gives perfect accurate values. I use it for a planted aquarium, it's light years better than my previous cept tests. It's more expensive, but I wish I had bought it 10 years ago....
