U.S. Solid 0.001g 1mg Digital Analytical Balance Precision Scale for Laboratories (200x1mg), RS232 Interface

.it is very touchy. need to practice. i needed better than .1 accuracy, this is it & i am getting good at getting it right on. VG, as long as it has longevity. time will tell.

I work in a lab and we have very expensive certified scales. I did not expect this cheap scale to match my lab scale at work. I took this scale to work so I could get a good idea of it accuracy. It's not close. And it will not repeat weight results nor hold a zero. I've calibrated it a bunch of time after it's set warming up. I highly suggest that you look for a better unit than this one. I am planning on returning this unit. It's nowhere close enough that I feel I can trust it for what I bought it for.

very stable, good quality, good price. this is the second one of the same balance I bought.thanks.

I use this to measure powder for precision rifle cartridges. I have found I need to verify the zero before and after each charge.

I like that I can get weighs as low as 0.0001. It’s underpriced in my opinion.

Ordered this product twice. Both units failed to weigh properly. Units both turned on, went into calibration, and changed units, but would not register any weight. Avoid this digital balance.

Works well for reloading

This is a step up from those whom have used the classic AWS-Gemini 20 mg scale that everyone and their brother has. It is sleek, and efficient. However with all things there are flaws.1) when plugged in, it displays that the battery is “charging”, like any other electronic device. However, when you attempt to use the device without a power supply it is just a paperweight, it does nothing. False advertising from the machine itself leading you to believe it may be battery powered.2) the 200g weight that was sent for calibration is handy indeed. However it’s hard to say if the weight is exact or if the scale is reading wrong. When placed on the scale, a reading of 200.3xxg shows and not a flat 200.000g. When using the weight on another, $20 scale from a local smoke shop it reads 199.5xg. So my assumption is that the calibration is off.However, then when weighing a supplement it seems to be right on the dot in comparison to the gemini20. So I’m really not sure why the weight makes such a difference between two scales.Pros:1) the best part of this scale is that because it is hardlined for power it does not have any “screen saver” function. You can weigh your item and leave it there forever and come back and see the weight displayed still. Most scales will turn off around 30s to 1m of inactivity.2) good amount of surface area for weighing, however I still use weigh boats.3) encased fixture to remove airflow from tampering the scale reading when in use4) lightweight, but sturdy when it is on the table. Doesn’t move unless you are intending to move it.Box description says minimum range is 20mg and that is false as it will start registering weight at 1-3mg of what you are weighing. Still, I would not say it is accurate, but it does weigh lower than 20mg.Tl;Dr- good scale, questionable accuracy but not too bad. Wouldn’t want to use it for extremely precise measurements, but within 5-10mg difference is okay in my book. Doesn’t turn off when you are in the midst of weighing multiple things.
