I got this refractor for my Opae Ula (native Hawaiian brackish water shrimp) and it seems to be pretty accurate. I wasn't worried about accuracy due to the shrimp's endurance. The only complaint is that the eyepiece seems pretty cheap and it's nowhere near calibrated when I received it (I fully expected it to be different from other reviews). Calibration was very easy, just a few drops of distilled or reverse osmosis water, turn the screw and you're done. I'll try it next time I need to set up a brine shrimp hatchery if I need it.
