220g/0.01 Scale

a very sturdy scale with magnetic cover (four little magnets on the lid keep it securely in place. its very easy to calibrate and comes with its own weight. love the bright display and arrived in about a day 2 days sooner than expected. with the recharble battery via the supplied usb cable what more could you ask for for 16 bucks. it also has one of the higher max weight and is very accurate. would buy again and again

Loved the accuracy of the scale and not having to replace batteries but today it was showing the wrong weight and after attempting to recalibrate using 100g weight(included) it showed 38.43 instead of 100, seconds later it started going up 38.43 38.44 38.45 etc. After the weight was removed. After turning off and and back on, with no weight or anything on it it starting going backwards -5.65 -5.66 -5.67 etc. And unfortunately continued to show random numbers and go up and down on its own with no weight on it. Scale was charged when this occured and it just continues to do so after numerous attempts to turn off, blow out anything that may have been stuck under tray etc. Very disappointed, was actually going to buy another today for a friend.

Great little scale for weighing low-weight items. I plan to use it for prospecting and weighing any gold I may find, but before that I checked the scale to see if it was properly calibrated. They supply a 100 gram weight to calibrate, but it's mass produced and it doesn't come with any sort of traceability to verify it's actually a 100 gram weight. Which is okay, I have my own NIST traceable 100 gram weight which I used to calibrate the scale. I'm happy to say though, the weight they provide is very, very close to being accurate, mine actually weighs 99.98 grams. So, not bad, but not perfect. Calibrating the scale is much easier than I thought, and once it was properly calibrated I played around with it using various known weights. It successfully weighed 2 grams, 10 grams, 50 grams and 100 grams successively. I let the scale power down after about a minute of not using it, turned it back on and went through the weights again, and everything was perfect once more. On day two it ran through the weights perfectly once again, no need to recalibrate the scale. Perfect! So, it's a little ugly with that faux-diamond plate cover, but what it lacks in aesthetics, it makes up for in accuracy and functionality. Color me impressed. Worth every dollar spent, and it definitely has earned a 5-Star rating from me. Disregard the naysayers and detractors, this little scale is amazing!

What amazes me is that not only is this a nice looking set but it also is rechargeable awesome Don't have to waste so much money on batteries and it's very good quality

We bought this scale because it promised enough precision to estimate the remaining length of a ball of yarn, while having enough working range to allow for the tare weight of a large enough tray and the typical range of weights where asking if enough yarn is left becomes and interesting question. Including an internal rechargeable battery was not a feature I set out to include, but is very nice to have. Worst case I will need to plug it back in to a USB charger if its been stored too long. And there's no need to worry about having stock of whatever obscure size and shape of battery my other scales all eat. Given that accuracy is important, we specifically selected a scale that included a check weight and a calibration feature, as this one does. That allows measurements made to remain consistent over time. Out of curiosity, we carried the provided 100 g calibration mass to an expensive (and calibrated) analytical balance. We were pleasantly surprised to find it measured 99.999 g, or only 0.001% low. That is remarkably good at this price point. As long as we protect it from fingerprints or other contamination that isn't likely to change. It is also about 10 times more accurate than the precision of the scale in typical use, so it is more than accurate enough to serve as a calibration reference. There are $1000 laboratory balances that are only a little better than this, and it is under $20. We are pleased.

It is accurate, sensitive, and precise. Know the difference? Accuracy is the ability to correctly measure a weight against a known standard. They supply a 100 gram weight and it is dead on. I also tested it with 1, 2, 5, 10, and 20 gram standard weights. Perfect! Using coins as standards is a bit problematic as wear, dirt, oxidation will cause detectable differences in mass. Sensitivity is the ability to detect small variations. This scale is accurate to 10 mg or 0.01 gram. You can't do better than this at this price point. Precision is the ability to get the same result measuring the same weight. Again, excellent precision. Bottom line: if you want an inexpensive, well built easy to use, accurate scale, this is what you want. My only ding is that while the included battery is rechargeable with the included USB , it is not accessible or replaceable. Given that, there will come a time when the battery will not recharge and you will need to replace the scale. This should take a few years.

Update: After 4 years of daily use this scale is still working fantastic. I still only have to charge it every couple months, it still reads great, and every time I check the calibration it's spot on. HIGHLY recommend. Very easy to read screen, rechargable so no more hunting for batteries, and has the calibration weight with it. The people bitching about the weight not being 100 grams don't understand the concept of calibrating the scale

I read other reviews that were most favorable so I expected a lot- and you delivered! Nice compact case, easy-to-read screen, simple calibration. I work in a kitchen that needs slices of cheese that weigh .5 oz so ease of operation is paramount. This unit will do quite nicely. Would definitely buy again. Quick delivery was a bonus.
