Scales have been good.

I use this to measure powder for loading ammo and this one measures out to one hundredths, 0.00 Grains. Has a 0.02 +/- accuracy. Can beat this for the price. I have seen similar items for 2-3 times more.

Took this scale into the Lab to see if it could pass our in-house certification and it wasnt able to. All of the work we do is in grains, and this scale doesnt have the resolution. It failed the 10g (154.324 gn) variance test outright. That test uses a special test weight (154.33 gn) to validate whether the scale uses a conversion algorithm or has proper resolution. The scale would not indicate 154.33 gn, would float back and forth between .32 and .34. To further validate, we went back to the standard 10g weight and trickled in cellulose powder, and it always jumped from .32 to .34. The scale was calibrated with with certified weights, and all work done done in an anti-static dead-air box, in the precision test (tare set each time), repeatability was just under 68%, which is below the acceptable threshold for precision lab work. In the batch test (not tare'd each time), repeatability was problematic. Beyond that, the scale is generally precise with some drift (need to stay on top of tare), but is still significant steps above common pocket/jewelers scales, its just not quite precision lab grade. For most other applications it should be fine.

This scale started off working accurately. Then over time, it will not "lock" onto a weight, even with the windshield in place and letting it "warm up".... Now, if you weigh the same item multiple times, you get multiple different weights. ALSO SUPER ANNOYING is that every 5 or 10 minutes you have to re-zero the scale... If you let the scale sit with nothing on the platter, it will mysteriously start weighing anywhere from -6 grams to +12 grams...even though nothing was placed on the platter and nothing was taken off of it... AS OF RIGHT NOW, THIS SCALE IS USELESS TO US...

I contacted Bonvoisin regarding the low accuracy and they told me that the error range is ±0.004g. This was not stated anywhere on the Amazon page. Also, the reading is often different on repeated trials, sometimes it does not return to zero after removing the item, and sometimes the reading keeps drifting. This scale is less accurate than my $20 accuweight scale that I also got from Amazon, and after import fees I paid around $200 for this one! I'm in the process of returning this item.
