This hydrometer is almost impossible for me to use. It works, but the labeling is broad enough to give you a "best guess" measurement. The only thing I like about it is that it's made of plastic and seems relatively indestructible compared to traditional glass devices. I broke a couple hydrometers while cleaning the beer equipment. The main reason you use one of these is to measure the beginning and ending sugars as accurately as possible to know the strength of your drink. In the image I provided you can see that the traditional hydrometer has a grid for every 2 points between 1.000 and 1.010 and again up to 1.020 and so on. This only marks 1,000 and 1,050 with only 1 grid between 1,000, 1,010 and so on. . Not very user friendly, visually not easy to use and frankly just a waste of time. I gave it two stars because the materials are strong and it floats and serves its purpose, but a 3 docked because it's more of a kid's toy than a scientific instrument. If I wanted to round the best guess, I wouldn't measure at all. Save money and buy a tool with more accurate dimensions.
