It has an extensive set of weights in a convenient (plastic) storage box. There are eight tiny square sheets that range from 10 mg to 500 mg, all with a raised end or corner to facilitate picking up with the included plastic tweezers. There are also eight solid weights: 1g up to 100g. I'm using it to calibrate my stylus force gauge, taking it on faith that the weights are accurate. At the price, it's not realistic to expect a precision set of weights, but perfection is the enemy of good enough.

The weights are great. They’re accurate and the weight range is perfect for weighing coins and such. The little case that they come in holds them secure and has a place for each weight. The one issue I had, which was resolved quickly, was a small weight was missing when I received it. The weight was so small I can see how it could have been overlooked. My advice is to use the tweezers in the smaller weights. They’ll slip from your fingers easily. Other than that it’s an excellent set. Highly recommend.

Very convenient to have to check the accuracy of your scales. I used 3 different scales to check the accuracy of the weights. They're spot on

All is good except for the tweezers to handle the metal weights. They are made of cheap plastic and don't have a good grip.

I should preface this review by saying that I do not have access to a calibrated lab scale with mg accuracy, which is what I would use to determine the accuracy of these weights: use them with a scale of known accuracy with lab-quality calibration.HOWEVER...I got them to test the sensitivity and accuracy of a small consumer-grade electronic scale that I bought here, which claims to be sensitive down to the nearest milligram. For 30 bucks, this is quite a bold claim, given that the ones that you'd use in a proper lab cost thousands of dollars.But I got these weights and that scale at the same time, and then followed the procedure for calibrating that scale using the two 10g weights it came with.Now this set of weights comes with a set of 1gram and above weights, all of which my little scale came in within about 5mg of the nominal value.It was the set of under a gram weights that I was wondering the most about. This set has 500mg, 200mg,100mg...all the way down to 10mg. Rather than taking the familiar form of a small silver metal cylinder, these weights are smallish metal squares. Some reviewers complained that these squares arrive all bent up, but that's a feature, not a bug. The upturned corner makes it easy to grab with the tweezers even when the rest of the weight is flat on the surface of the scale. Which you definitely want to do, because if you even breathe hard on the smallest weight its liable to go flying off into the cat dimension, never to be seen again.Anyway, I was able to determine that my little scale does have milligram level sensitivity, however, the accuracy of it is probably +/- 5mg. Which is fine for my purposes, because for the stuff I am working with, I need to measure small amounts of stuff in the 250mg total weight range. So if what I can get is 250mg +/ 5mg--so long as the error is relatively small and more importantly, known accurately--one can usually work with that.If the level of your need for accuracy is truly down to the single milligram level, then you're going to want to pony up the money for a lab-grade set of calibration weights, and you're going to pay at least ten times the money that these weights cost.
