The scale worked well the first day, was easy to calibrate and agreed with my NIST weights. Second day of use, not so much. Developed a small and somewhat odd drift, became difficult to maintain repeatability. I tried the anti-draft box that comes with it, and made the scale somewhat erratic in its readings when installed. At that point I placed the entire scale in a dead-air box just to make sure it wasnt some slight draft, or static build up, but same result. These type of scales should always repeat with minimal amount of tare's required.
