Hi Ed,
I too just bought the same scale and got it Monday. My testing was not quite a thorough (turn it on, test with the calibration weight, go with it)... LOL. The calibration weight they shipped was 500g, and it was exact consistently. I don't know for sure the weight of anything else so trying to calibrate or test accuracy was irrelevant.
I measured the heads from Wishon that I bought and they were each .4 to .5 grams too high compared to the sticker on the cellophane. Then I removed the cellophane and bingo, apparently it weights .4g. (What a newbie eh?).
It's been great having a scale as I built this set and now I wonder how I did without it. I caught a major gaffe (sp?) in my prior technique with predicting swingweight in that the grip I used doesn't way close to the final grips and I never put two and two together. I took an old grip, trimmed off enough rubber to match the average weight of the grips I was going to use and voila, the readings this time should be closer to reality. Funny how something so simple doesn't cross your mind sometimes - and it's so obvious a thing to cause a difference too. Oh well.
I chose to buy digital instead of a triple beam because of the time savings for me... and realize I paid a premium for that but overall this seems to be a great scale and will be a valuable addition to my workbench.
I bought it from Canadian Weigh (canadianweigh.com) and received it promptly... pleased with the process.

Bottom line. It appears the scale is VERY repeatable and accurate. The only issue seems to be a slight sensitivity to temperature. (The scale does have compensation for temperature changes). However, you can simply check for a possible anomaly with the calibration weight and easily perform a calibration if desired.
