Query: Mine was wildly inaccurate!

I bought this on the basis of reviews, looks, and a great half-price deal. All seemed to be well for a while, until I had occasion to measure some liquids in a cup. When it took much more than 16 liquid ounces of water (remembering the old high-school physics reminder, "a pint's a pound the world around"), I became suspicious. Some more semi-scientific inquiry (i.e, a couple of 500-gram bags of pasta from the store) made me realize that this scale consistently measures 25% light! No amount of adjustment and tweaking (I even tried "stretching" the coilspring by over-turning the adjuster) made things better. Sorry, but, aesthetics aside, scales need to do only one thing well, and that's to weight stuff accurately. 5% error is (somewhat) forgivable; 25% is a joke. Too bad I tossed the box, but I'm still going to look into a replacement or refund.
