This tool was exactly what I needed to keep track of my fish tank's levels. Excellent purchase.
This method is ineffective. Fresh water and highly salted water do not have a ppm level of zero. Make sure you don't throw your money away.

Refractometer arrived in a nice case with pipettes and cleaning cloths, and it works fine. I did receive calibration fluid, and it wasn't quite calibrated from the factory, but other than that, I'm happy with my purchase.
Accurate. Simple to work with. It's a lot more precise than a cheap plastic hydrometer. The only issue I have with it is that the scales' numbers are extremely small and difficult to read. I would strongly suggest it.
We use this item for school projects because it's so good.
This item has been very accurate during my use of it for a few weeks. I checked it once a week with distilled water to ensure it was properly zeroed.
To check if the calibration is at or near zero, start with some tap or drinking water.
