I have an expensive OHAUS N12120 I got from the pile of broken scales at school (back when I went to school). Just needed a couple leads inside resoldered! But my point is that a buddy of mine got a 10mg palm scale (like yours) from a smoking accessories store, and we spent about a couple beers worth of time measuring junk around my apartment. They are pretty much the same -- if you breathe on mine it changes the weight (seriously) but they settle to the same. In fact I have thought about downgrading just to get the space back on the counter I keep my nerd stuff.

The easiest part is you can put your ferts onto the plastic case and never have to get them onto the scale itself. It was designed as a gunpowder scale, so the small granules to be weighed were thought out well.
