Salifert test kits: good accuracy but terrible quality

[lastlight]

there should be enough quality there for the markings to last as long as the disposable product is supposed to that's his point.

i've always been happy with elos.

Salifert has always been hit or miss, they had substantial problems a few years ago. I use Elos or deltec....never had a problem. I never rely on one brand though.
