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.
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. .
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.
This scall changed all that. It's fast, and it is consisent.
I measure airgun pellets down to to .02 grains (18.10, 18.12, 18.14). It works great.
