Works for the price

This product does what it does, and does it well, and is cost affective.

Five Stars

Excellent easy to use and read super fast shipping

Works great

Works great the reading is actually the same as my hydrometer.

good price and works

I may update this review in the future once I can compare this device's reading to others.

Quality, and accuracy is very impressive for the cost.

Has a quality feel for the cost. Sure a $100 refractometer might be a little heavier, etc.. but this is solid, and functional at a very low price point. The visibility through the scope is great. Since the thing uses the principles of physics, I imagine once calibrated well, it's going to measure salinity as well as anything can. Mine came not calibrated, but not a big deal, things get bumped in shipping. Calibrate it, use it. It's good. Seems like every $20 refractometer is the same thing on amazon, so I imagine if you get one that looks like this, it's probably the same. I expected the case to be absolute crap with a molded hinge, but it's actually not too shabby and will definitely keep the unit safe.

Great product

Works as its supposed to. Just as easy and accurate as the expensive ones at the fish stores
