KUBEIUSB Rechargeable Digital Milligrams Scale 100g x 0.001g High Precision Jewelry Scale Reloading Professional Mini Digital Pocket Scales Portable Electronic Scale Weight Grams and Oz

Great scale! comes with its own calibration weight, and rechargeable lithium battery. Im also very satisfied with the repeatability of readings. Im very happy with this product.

I used this to measure out flea medications for my dog. There's a bit of a learning curve to using it if you measure extremely small amounts because the numbers fluctuate in the thousandths place after a few seconds (eg for 0.123g the 3 fluctuates). After a few tries I was able to do it quickly enough that the numbers didn't change.It worked great until I accidentally dropped it while it was closed and inside the fabric pouch. Sucks that now it's broken and unusable. I either get some kind of error message or it doesn't measure correctly. Be super careful and do not drop it!

I use the scales to weigh gems stone and metal for pricing

On the first day of unboxing the scale I tried everything to make it work: charged the battery fully, set on level granite slab, calibrated it 3 times. Nothing I tried would bring it to zero. Tare wasn't working. Weights way off and not repeatable. Finally decided to return and got so far as to get a return label. Then I thought I'd go over it one more time to see if I missed something. Long story short a tiny bit of metal tape was found between the shiny metal weigh pan and the top of the plastic housing. Removed with tiny tweezers. After that everything has worked flawlessly. Calibrated fine. Tare button just takes a few seconds. The scale seems to dampen in about 3-4 seconds. As expected it was affected by the furnace coming on but when it went off it dampened out right away and returned the tare weight to zero.I bought this as a double check to weighing reloading charges however it is so efficient I may use it to do the actual weighing and use the other scale as the check. One drawback for this purpose is that it is advertised as accurate to within .001 gram which is .015 grain. HOWEVER, when you switch mode from gram in thousandths to grains, it only reads in tenths. This doesn't sound like much but when working with the difference between 3.2 and 3.3 grains (32 auto) or 4.6 and 4.8 grains (.455 Webley), more accuracy is important. By converting the grains to grams I can take advantage of the half tenth of a grain accuracy rating of the scale. That would at least tell me if the charge is closer to 3.2 or 3.3.I tested the scale at 5,10,15,20,25 and 50 grains. At 5 grains it is within 1.4%. At 10 grains it is within 0.4%. The rest were within 0.2%. That combined with the quick dampening rate result in a very useable tool. If the grain mode had the extra digit (hundredths) it would be a 5 star tool!

I use it for extra precise weight measurements. As long as it's treated gently it should do the job for a long time. It was a good purchase and I'd buy it again.
