I have owned the Pinpoint for over a year. Mine works great and seldom needs calibration. (off by .01 after two months is inisignificant to me). I no longer have time for chemicals which take too much time and are too general in their readings. (I'd rather be setting up spawning tanks or doing the 'Net.) When I was doing the chemical testing, I didn't do it very often and could lose fish as a result. Now I can get a quick general reading in about 10 seconds per tank! ...or a minute each for a more stablized reading. --Randy alex pastor wrote: > I need some feedback.
