Query: The Postal Scale

when I first hooked up the scale it only registered in grams and kilos, not ounces and pounds. I emailed the company and they did not respond for 2 weeks. Very unprofessional to me. In the interim I figured it out and the scale works fine except that when standing for a while (plugged in) it will resister 1 or 2 ounces with nothing on it. I'm thinking of getting another one directly from the post office. Allan Palmer
