Bought to replace an old pendulum hydrometer for my marine aquarium. The device is accurate, I have tested and dialed it with calibration fluid and also double checked with my hydrometer. I am concerned about the design of this refractometer. It feels plastic and cheap in the hand, it doesn't weigh that much. A plus is the fact that it comes with a hard plastic storage box. There are foam inserts in the case, so I think that with proper care (dry, cleaned, etc.) it will last a long time.
