Hobein First Impressions
Calibrate it, use it.
And always make sure there is no bubbles on the measuring unit. When I compared it to what my local pet store was reading my water at it was dead on. Be sure to adjust the focus by turning the eye focal when you first receive. Plus it is super easy to use and clean. Be sure to adjust the focus by turning the eye focal when you first receive. Was calibrated and worked perfect right out of the box. It is easy to read and perform the procedure in seconds.

Hobein Final Thoughts
This tool does that.
Even the smallest bubble will throw the measurements way, way off. It came with all that was listed in the in production description. All very easy and I feel as though I am getting an accurate salinity reading. So once your instant ocean shows a measurement. But there are some ways to keep on getting accurate readings. Too that makes it appear too cheap. Excellent piece of equipment for the price.
