Remarkably stable, accurate and reproducible within certain limits (see below). Magnetic closure for the lid. As with all battery powered electronics, I remove the batteries when not in use to avoid batteries which sometimes leak acid and damage the electronics. Update: Decided to calibrate it, after that it didn't recognize the weight in the 0.00X gram range. , so I calibrated a second time following the instructions and then it worked, I could measure a piece of plastic that weighed 0.008 grams and I could remove it and put it back in and the scale showed 0.008 again. Very reproducible BUT it only holds the reading for 30-50 seconds before going to 0.000 and if you remove and replace the weight it reads 0.000 or -0.008. Now if you just turn it off/on and weigh it again, it will show up correctly again within 30-50 seconds. Therefore, the scale is very sensitive to drafts (like your breathing) and vibrations, which is indicated in the instructions. In the 0.0x gram area it will slowly drift to lower weights and if you remove the weight you will see -0.00x grams which is the amount it has moved down. I only need it to be accurate to 0.X g, and it's very stable in that range. Note: when I put the batteries back in it turns on automatically and keeps giving a bowl overload message (probably because the scale is upside down when I turn it on), so I turn the scale off/on and everything is fine then. Also to tare, press the tare button for just 1 second and then release and wait for it to reach 0.000. If you press and hold them longer, it will show 180, and then you have to turn them off and back on to clear them. I am using this to measure the ingredients for a pizza dough recipe where all the ingredients were in grams (real Italian recipe), yeast, sugar, salt and oil were in the 1 to 20 gram range hence this scale has since put on Works great Gram table/teaspoons cannot be converted. All in all a real bargain.
