Overall good product. App is easy to use. I do wish some of the parameters would give an actual reading rather then “LO” or “HIGH” so I know how far off I am. Example: Calcium “LO”, I want to know how low. I also don’t like that each individual test on the app costs $. Example: nitrite strips cost $12, but to download the test, it was an additional $5 to download. That was disappointing. I did purchase the “marine bundle tests” to download, that was $25. Didn’t include nitrite which is critical when cycling a tank.
