Exactly, a lot of stuff geared towards this hobby is pure fluff and waaay overpriced. IMO if it reads 0 in bottled water, it works good enough to judge when to change my filters. Mine gets used every 6 months or so, when the season changes. I tested mine a month ago, 2ppm, change out media, double check with the wifes bottled water, reads 0ppm. End of story, back in the drawer till march or so.
