What test kit 'model' doesnt require repeat purchase of reagents, etc? Im just curious - because they all do - now - maybe theirs is more expensive than it should be - IDK - but this seems to be odd. It would be nice if you described why you think coralvues monitor dosing combo looks attractive, when its coming out, whether there will be a delay *(like there has been with trident - due to high demand), whether its accurate, how much maintenance is required etc (note - not a snarky question - but a real one) - though discussing it may 'derail the thread'. Coralvue, IMO - is not exactly a 'sure thing' either.
