Checked against Tropic Marin precision hydrometer. This was after shaking well and trying several attempts. I see great reviews for the smaller bottle. This was the large bottle. Why 3 stars? Because it was pretty consistent to 30ppt, which if you know this, can still use it to calibrate your refractometer. But you could throw 25ppt if you trust it as being 35ppt as stated. Use with caution, and multiple references.
