I don't know if it applies to scales, but here's my story about digital calipers. Several years ago I bought one from Harbor Fright Tools. A friend was going to be visiting from Europe, and he really had his heart set on a genuine Lyman digital caliper, so he ordered it and had it delivered to my house so it would be waiting for him when he arrived.
All worked according to plan. Then we opened up his genuine Lyman digital caliper and held it next to my Harbor Fright digital caliper, that cost less than half what the Lyman had cost. They were IDENTICAL. I'm certain they both came out of the same fafctory in China.
