Slick looking small milligram scale. This could technically be a pocket scale but is better suited to carrying in its provided box, the lid of which is retained by magnets to allow quick easy opening but keep it closed otherwis. The measuring surface by itself is not very large and is better suited to using the saucer that comes with it or something like SEOH Plastic Hexagonal Weigh Boats Micro Dish 100pk which I have bought myself. The Seoh boats provide a larger container then the provided metal saucer. I compared this to an older Ohaus digital scale I had that only goes to .1 grams and they both seemed to match. The provided calibration weights seem fairly cheap. They are not solid and the bottoms seem to be poorly glued on which retains the fine material inside that apparently allows them to tune the weights before shipping. You can pick up and shake the weight and hear the bits bounce around inside. Actually upon opening my box the piece of scotch tape on the plastic bag holding the scale had a few metal bits stuck to it.I was confused where these came from until I pulled the calibration weight stuck in the box out to see the bottom missing. See my photos The real problem to this is when the scale first arrives you will probably need to calibrate it. However to properly calibrate requires BOTH 10 gram weights. So this left me in a bit of pickle where sure I can compare the first 10 gram weight to the 2nd damaged 10 gram weight but since I could not properly calibrate the scale to begin with I am unsure if this comparison is accurate.... I glued the pieces in and it looks like I may be off around +/- .003 grams or so. I considered requesting an exchange or a new set of weights but it seemed like a lot of trouble. I may end up picking up some higher quality calibration weights later but they would likely cost more then the scale itself. Another issue I have is I wish the scale would stay on a little bit longer or have an option to stay permanently on or at least an extra minute or two. You really have to have everything setup and ready to go as soon as the scale is turned on and your weighing container is tared. Conclusion Pro: Cheap, accurate, nice looking scale. Including calibration weights, weighing pan, tweezers Con: Poor calibration weights - one of mine arrived damaged, weighing pan fairly small - recommend purchasing plastic weighing boats Read more

I ordered this scale to weigh capsules from a compounding pharmacy. My suspicion was that the drug-to-filler ratio was varying widely. Since one ingredient weighs more than the other, if some capsules in the batch weighed a lot more than others did, there was a good chance I was getting an inconsistent mix of filler to drug. When the scale arrived I followed the calibration instructions (easy-peasy!) and then started weighing the capsules. Yup--big difference. So I took the scale in it's sturdy box and some capsules down to the pharmacy. The pharmacist viewed me with an expression of polite and slightly condescending patience, an "all right, I'll watch--then I'll show you that your cheap little toy doesn't weigh correctly" look. I weighed some capsules and he wrote down the numbers, then took the capsules into the back room to weigh them on his very expensive and accurate scale. When he returned, his look had changed to stunned interest. He asked where I got the scale and how much I had paid for it. He said he was going to recommend it to his customers, who had asked him where they could get an affordable and accurate scale. Yeah, the little round weighing platform is small, but it will accommodate a small pill very well. I didn't have any troubles with the little dish as one person claimed they did-I bet they didn't point the dish's pointed spout towards the calibration weight. That makes a difference! This scale is the REAL DEAL, and does the job. Just read all the instructions and follow them step-by-step. TIPS FOR ACCURACY-- 0) Read the 4 star rating for additional good tips. 1) Calibrate often, as this is a delicate instrument. Calibration is pushing a button and adding 2 weights (included). 2) If you are weighing a capsule or powder to use the little dish (included). 3) Be sure to point the spout on the dish directly at the calibration weight which is stored in a little holder on top of the scale. This scale is VERY sensitive, so if the dish always sits the same way, it will weigh the same each time. 4) When weighing capsules, point one end towards the same stored calibration weight also. That way your capsules and dish will always be in the same position, giving you more "sameness" when weighing things. 5) Always put the scale and accessories (extra calibration weight--you need both to calibrate but one stores on the scale and one in the box--and long tweezers) in the box when done with them. This scale probably won't survive banging around or being dropped on the floor, so put the box where it won't get knocked off a shelf. Read more
