> 3 daySad to say not pleased 1 probe will not calibrate in buffer 4 on the slope . USA is to far to send back the probe hence one star.

> 3 dayI bought this in February of this year. It will not take an accurate reading. Ive calibrated it on numerous occasions but it repeatedly reads low. Not worth the money.

> 3 dayI have used Pinpoint PH monitor for 15 years from saltwater aquarium to freshwater aquariums. The probes have always been easy to calibrate and last. However the probes from this company are temperamental and the bulb on the end always seem to break. After owning 2 of these now in ~18 months my opinion is they are of poor quality. And the package is poor, makes me think they are used. I would rather spend the extra money and get my probes direct from American Marine

> 3 dayPINPOINT. This is my go to replacement brand sensor for my reef tank monitoring system. Have used many over the years. Very reliable, high value.
