Why Weight?
If you're like me and need accuracy in your kitchen scale—and are always wondering if it's really accurate—then these are your Huckleberry. The weights are easy, accurate and jibe with several scales I've tested. They're also a bargain for the piece of mind they give you.

Nice set of Gram Weights
It is a really nice gram weight set. Will be using them to set up my turntable to confirm cartridge weight. The reason for 4 stars is the 2 - 20mg weights - do not fit in the slots made for them. Also be careful, opening the case, the weights are not in snug and fall out

Except for the cheesy tweezers it is impressive.
Well, first of all I cannot speak for the accuracy of the weights. It is surprising that there is no form of document included attesting to the accuracy of the weights. There's not even I little slip of paper stating "Inspected by..." So I'm accepting the accuracy as stated by the manufacturer. The video shows a scale I was checking and not once did the displayed weight deviate from the calibration weight by more that 0.1 gms. Was it the scale or the weights? Based on the performance of other scale features I would put any inaccuracy on it and not the weights. The tweezers are really cheap and distracting from the rest of the set. The plastic is too thick and makes picking up the smallest weights difficult as you cannot grab the bent corners tightly snuggled into the depressions. The video shows even picking up the 1 gm weight by the knob was slippery. Surely the manufacturer could have included some better performing and better looking metal tweezers. I considered dropping a star due to the cheesy tweezers but it's not like I use them all the time.

Perfect for weighing small amounts on a cheap little jeweler's scale.
Does exactly what I needed. Most inexpensive scales only go down to around 40-50 mgs... this set allows you to go as low as needed. Great price for all the weights & nice, sturdy box to keep them in. Recommend!
