    • SATISFIED WITH PURCHASE
Cannot determine accuracy, but results are consistent when solution is shaken well.

    • A Must to Calibrate for Refractometer
If you are using a refractometer you need to calibrate/verify it from time to time. This solution makes it very easy to to do. Just a couple of drops and you are good to go.

    • Good cal solution, crappy childproof cap.
This product does what is on the tin, but is packaged with a childproof cap that cannot be used as the neck and top of the bottle collapse while pushing down to open it...it's f'ing saltwater there is no reason for a childproof cap especially one as poorly designed as this.
