Service
There is not much to review. For the operation no manual is needed. The few and sufficient functions can be used intuitively.
Accuracy
I have done no costly cradle series, because I totally sufficient accuracy to 1 gram. The achieved the balance quite loose and it is still more accurate.
Application
I have withdrawn, because the height of the scale could be significantly lower a star. A more elaborate placement of the battery compartment, the balance could be only half as high. A little unfair that's from me, because I need the lowest possible height for my purpose, most of the others is hardly interested. I use the scale as a tone arm for my turntable. Specially Designated as a stylus balance scales of course there are, but the cost many times and do not also or are not accurate. For those for whom the height does not matter who like to add a star to.
