My one is very temperature sensitive. As it gets cold when stored, I make a jug of 20 Celsius water and stand it prism-end down in that to warm up ready for use. It also seems to need calibrating before each reading.
Hydrometers are great.
If I could just find one that is unbreakable I'd be in wort viscosity measuring heaven!
I did see a plastic one for fruit juices but the scale was well out for beer puroses. They do work on a very simple principle of differential floatation though - I wonder if I could make one using a true hydro as a reference source for the initial scaling......
