Hanna should be more transparent on the acceptable range of error of their instruments. It is what it is. Not perfect.

The website can be a bit confusing when ordering reagents, especially when trying to ensure compatibility with your specific tester model. A clearer layout or guided selection process would make it much easier to find the correct items.

Works great. Packaging and certification was gave it an authentic feel. Came with everything I needed to get started. Would be 5 stars if the device user interface was easier to navigate. There are only two buttons on the machine which control power, mode, calibration, units, etc based on if you press them quickly or hold. One press of the left button turns it off. Long press the left button to enter calibration. But as you long press, the display reads OFF the same as a short press, before entering CAL mode. . . May invest in 1-2 more buttons and a slight chip programming upgrade in my opinion. . .
