Darn you for showing me something else that’s better than what I have. Must resist...but it is tempting.
Well, the OP did ask for the "Best" It is very accurate and super easy to use. Calibrate once and done. I check it once a year, but it has not needed recalibrating. Just push button to turn on, put in sample, close lid and push "Go" button. It is accurate to .0005 and goes out to 4 decimal points!
