Float hydrometers should be preferable to this pointer unit, but floats aren't as accurate or consistent as they used to be. Just my opinion after recently buying two floats, one expensive, one cheap.I'd like this Ezred better if the bulb were a bit larger and the scale more complete, but at least it gives consistent readings if used properly. I suspect it reads a bit high, but still in the ballpark.
