Bests & Worsts Reviews from Amazon

Bought this following the very good review from the NY Times Wirecutter. Received the KD8000 Scale and initial impression was positive. Scratch on the display face was minor annoyance but wasn't enough to want to return it for another. The inability for the scale to keep the weight displayed steady when an object was placed on it was a deal breaker. A solid object placed on the scale would slowly drift higher in weight, return to the original weight then drift lower in weight. This swinging of the displayed weight was unacceptable. I had used the tare button prior to placing the solid item on the scale. Read through the included manual and followed the suggestions of making sure the scale had been in the room for an hour so that it could adjust to the room temperature, wasn't near devices that generate magnetic fields, not near heating or cooling vents, surface for the scale was flat, etc. Placed my two coffee scales Bonavita and Hario V60 with the identical solid weight on each one and the weight displayed held steady. I expected the KD8000 to do the same and it wasn't. Returned the KD8000 to Amazon and asked for a replacement. I liked the potential for this scale, liked the Wittercutter review and thought that this was just a bad unit. Replacement arrived and have the same problem. Display value drifts up and down. Returning to Amazon.
