Review on UCEC Calibration Weight Kit 10Mg by Sean Young

It seems to work great. Some of the stamps are hard to read but I've adjusted them to make it easier. The lid hinge, which is molded from the same plastic material as everything else, begins to fatigue and break with even minimal use. I'm sure I'll have to use a rubber band to hold it all together soon, I'm sure. I have no way of verifying the scale's accuracy, but I think it's fine for my purposes.
