This cheap Chinese scale was off by as much as 80%!

Sometimes, even so-called "inert" ingredients in dog meds can be harmful to cats, even if the active ingredients are the same, so best to never mix cat and dog meds.

I most often use it to measure 10-20 mg of substance, and I have no doubt that it's accurate enough for that use.

I just received this scale and set it up. I followed the calibration process per the manual, using the two 10-gram weights. Once the scale displayed that the calibration was successful, I checked to see that the scale read zero with the weighing pan in place. It did. I placed one of the 10g weights in the pan, and it showed a reading of over 16 grams! I removed the weight and the scale zeroed, then placed the other 10g weight in the pan. It showed over 18g.

WTF?

I repeated this whole process several times, with the same disappointing results every time. Each time I would weigh either of the 10g weights, the display would show a completely different amount, with values ranging anywhere from about 13 to over 18 grams. This cheap Chinese scale was off by as much as 80%! Apparently, it's only accurate at zero. :(

This is completely unusable junk.

Once you read this i think you'll understand why I'm comparing this to a lesser precision scale.

This scale is not very accurate. I find the AWS-100 with only resolution out to one hundredth of a gram to be more accurate weighing milligrams. Yes, MORE accurate weighing milligrams.

Let me explain. With the American Weigh AWS-100 the accuracy is perfect out to one hundredth of a gram. It's perfect with my 100g M2 weight(10.00), 50g(50.00) M2 weight, and 1g(1.00) M2 weight. That equals +- 10mgs. Although it takes about 30mgs to register..

The Weigh Master Gem Scale when weighing the included 10g weights(which repeatably weigh 10.01 and 9.99 on my AWS-100) weigh anywhere from 9.825 to 10.215. Both weights will vary like this after each calibration.

I'm not using the included weighing cup and only weighing on the scale on a solid oak bench. No air breeze is affecting the readings as i can literally blow on the scale and it has no effect. Nothing I weigh is repeatable to within 20mgs.. .

This scale has no useful purpose for me. It's possible I got a lemon but i don't think so after reading some of the other reviews as it seems it is generally accurate to no better than 30mgs. .

Original review (important update below): Often, dog and cat flea and tick pills have the exact same active ingredient(s), even though the cat medicine often gives you far less of the active ingredient for the same cost as that much higher dose dog medicine. Thus, you end up paying far more (as much as 80% more) for cat medicine versus dog medicine. So, when a pill can't be safely broken up into proper, smaller doses using a pill cutter, it is possible to crush (using a mortar and pestle), divide and weigh it using a sensitive scale such as this one. However, one would need to be careful in their calculations; also in making sure the scale is properly calibrated (using the weight provided); and careful in making sure that they are weighing the medicine properly (the included tweezers can help). I'm not saying it 'should' be used for this, as it is designed for gem use, but saying it is certainly one possible way it 'could' be used by someone if they wanted to.

Update: I'm updating this to "be very careful" if using this in the manner described below. It's really NOT recommended, as it's very easy to make incorrect calculations and cause harm to a pet if you don't know what you're doing. I was going to delete this review altogether, but figured I'd leave it up as both a positive review for a terrific scale, and as a caution for anyone looking to save money on pet meds. It's too easy to make a calculation or weighing error when dealing in such tiny doses -- or any doses, really -- so I would recommend just getting the correct dosage for your cat or dog and not using dog meds for cats. Sometimes, even so-called "inert" ingredients in dog meds can be harmful to cats, even if the active ingredients are the same, so best to never mix cat and dog meds. My apologies for this update. It's out of an abundance of caution, as I'd hate to see anyone make a mistake that harms their pet.

I bought the scale for reloading. While it seems accurate & easy to calibrate, the included tray is somewhat small & might present problems for reloaders wanting to load larger calibers. For my application, generally loading nothing greater than a .308, the scale is working out fine.

It might show my date of purchase, well - I can still use this scale today and it is very close to perfectly accurate. I've had to use it for mg amounts of supplements and it did a good job.

As a beginner with a little prior knowledge and guidance these are perfect. I do plan on upgrading but these were reccomended to me as a starter set or even just as a travel or back-up set and I am very pleased. I plan on checking into some of their higher end set when I decide to invest in a set.

Works good. Cycles off to save battery a little fast. Can't beat this scale for the price. Works for my reloading needs.
