Query: Great little scale

Functions well, uses AA batteries, has a tare option. This is a fantastic scale for the money. Be warned, though, that it's not great on tiny increments. If you want to measure 1 and 2 gram quantities (I was hoping to measure my loose leaf tea by mass - I'm a geek), you should probably look elsewhere. For baking, postage and other standard uses, though, it's perfect.
