Anyone have one they recommend? I have one that I have been using for I would say 5+ years and I am starting to lose confidence in it. When compared to a hydrometer lately it is never close. I tend to use it for mash and pre-boil. The last couple or brews it is giving me the same reading for gravity at the end of the boil as it did at the start. These samples are all cooled. I do not mind paying for a good one as long as it will last.
