The MY MIRONEY 2-Pack Salinity Tester Sea Hydrometer Salinity Meter Specific Gravity Test for Aquarium Fish Tank Water Marine Saltwater seems to have mixed reviews from customers.

This raises concerns about the calibration of the devices and the overall reliability of the readings. However, another customer explained why they continue to purchase these hydrometers despite their shortcomings. They mentioned that while they have other measuring devices like refractometers and an icecap salinity pen tester, they prefer using the MY MIRONEY hydrometers because they are more convenient to use. The customer emphasized that they use the other devices to ensure accurate salinity levels and then rely on the MY MIRONEY hydrometers for ongoing monitoring. They also mentioned marking their own measurements to compensate for the inaccuracies of the hydrometers. On the other hand, one customer had a negative experience with the product, stating that both of the hydrometers they tested were significantly off and ended up causing harm to their fish. Overall, it appears that the MY MIRONEY 2-Pack Salinity Tester Sea Hydrometer Salinity Meter Specific Gravity Test for Aquarium Fish Tank Water Marine Saltwater may have reliability issues with its calibration.
