Doesn't hold calibration very well. With every use and even with several measurements on the same day, it has to be recalibrated. Focuses well. The scale is clear and easy to read. The alcohol scale is slightly different. Brix x 0.55 is the correct estimate of alcohol content. This device reads about 10% lower.
