Must Have!!!!!
We've needed a refractometer for some time. After searching and searching, I decided to come to Big Show Frags For the Salinity Pen. Once received, my husband fell in love with it! It's simple to use.

amazing
Went from 2 instant ocean hydroneters tbat read different numbers consistently. Not just different from each other, but even after tapping bubbles out I'd never get the same two readings... Got this guy and love it. Only complaint is I should have purchased it sooner
