Pros: It's accurate and compact. Comes with batteries and is very quick and response. You don't have to wait for the scale to settle or adjust. I plan to use mine for making arrows to correct mass, and for cooking.
Cons: limited maximum mass only 100 grams, but what can you expect for something so small? AAA batteries suck to replace, would have preferred AA batteries.
Other Thoughts: It seems to do its job quickly and precisely. No complaints so far. Great for spices and herbs. As well as measure ammunition mass
Bottomline: If you need to measure the mass of small low mass objects like sand or bullets / arrows it works great. Really cheap too.
