1.0 out of 5 stars Not a good scale

.. · June 19, 2023

Maybe the one I sent was faulty. Asked for a replacement. So far its not looking good.After unboxing the scale was pluged into the wall outlet using the provided power plug and then calibrated using the provided weight. Calibration is faulty. After multiple attemps, the scale would always report the calibration weight to be off by -0.352 to -0.291 gramsUsing a seperate scale, the calibration weight was measured at 200.00gTesting with 2 different certified weight sets generated the same resultsBetween 200.000-25.000 grams the resolution was only 0.25g. Addition of anything less would not change the readings.Below 25g the scale begains to drift, increasing by 0.001g per second. After 5 minutes the 25g weight went from 25.141 to 25.461g. And the scale was still counting up.Accuracy was tested200-25g 0.15%25-1g 1.6%1.00-0.500 2.4%0.500-0.100 30%0.100-0.010 65%0.010-0.001 70%The test where then performed by using a fresh 9v battery instead of the wall plug.The results where the same.Another note, after every weighing, the weight was removed and the scale would not return to zero. It would always show between 0.1 and 2.0g and have to be zeroedThe battery cover will not snap into place with a battery in the compartment. Its simply not big enough.The scale has no manufacturer lables, not even the voltage of the power input. Nor does it list is weight range or accuracy values.Update:After receiving the replacement, it was subjected to the same testing with the same results. This is not a milligram scale. At best, the resolution is +/- 0.250g

4.0 out of 5 stars Decent low cost scale for high school or middle school labs

Purchased for local high school for use in science classes. There are some issues with the scale that surround the draft box. First level the scale and make certain there is NO corner to corner movement when you put light finger pressure on opposite corners. When I used the draft box lid, the scale becomes unstable which is counter intuitive. Until that is I realized that the box sits on specific pressure points at the four corners and has enough weight to impact the force sensor inside. I removed the draft lid permanently, calibrated it again, and it has been fine ever since. I put the draft box on again, and it became unstable. The outer case is NOT strong enough to stop the interference with internal workings. I verified this by putting a small amount of pressure on the four corners with fingers and sure enough it became unstable exactly as it was with the draft lid on. Took the lid off permanently and set it to the side. Scale has been calibrated and stable ever since without issues.

5.0 out of 5 stars It's definitely sensitive and works well...

N. · June 13, 2023

But I was concerned when I got it. It only has a paper with terrible (or lack of) instructions. It looked like a return, but I wanted to give it a chance. There is NO company name on it, so nothing you can look up about it. With that said it was a learning curve. You have to let it go through the startup process for a minute before using it, don't rush it. Long story short, it works really well. I have multiple weights to test it, very sensitive, and use the shield if there is the slightest air movement. Strange there is no company name or anything, usually someone slaps on a name and calls it theirs. Not sure if I did the right thing in keeping it, but it works and I figured out everything myself with trial and error. Time will tell if it is worth it, so I'm holding out hope it'll last.
