Bought new off Internet for testing my aquarium water. Worked sorta one time. Hold button failed to "hold" and then when I went to test a second time the unit failed to work at all. Turning on, I get the backlight on and then three dashes. Hit the on/off button to turn off and it doesn't turn off.
Maybe it is usually good, but the one I got is a piece of shite.
