Gemini-20 Milligram Scale – 20g x 0.001g Precision Digital Scale in Silver & Black – Includes Calibration Weights, and Tweezers – Ideal for Jewelry, Labs, and 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.

This scale is exactly what I needed. If you want the short version of this review then simply put, BUY IT. If you want the longer version then just keep reading.This product came exactly as described and is a very easy product to use and is very accurate from what I understand. The way the product works, is you open it up and turn it on, then press the tare button which will set the scale at 0 calibrating it for whatever is on it. An example would be if you used a small cup style thing to put a product in to weigh it and it not get all over the place. So you tare it off with that product on top and it will show zero and not count the weight of the product holding the powder etc. Then you put it in and weigh it off.The look of this product is beautiful and exactly what I am wanting and looking for. It is very very small and compact and I keep it inside of the little box that it came in for protection. This could be a useful tip if you plan on traveling with it. When I put the 10 gram weight on it just to test and see what the scale would read, it would say around 9.9 so I would assume that It is just saying that it is only.001 off of what it needed to be or something along those lines. I would read into this a little more for a better understanding. But if you are looking for a quick and easy weight that you can use to measure some things out, this is for you. If you are some nit picky scientist that is looking for exact down to the wire no margin for error weighing then you may want to pay for a scientist quality scale. But for the average user weighing out nootropics to put on a pill then that is all you need. Good luck and thank you for reading my review. This is a great product for a new or average user looking for something quick and easy.

*********WHY I PURCHASED THIS SCALE***********I purchased this scale so I could weight out various Nootropics supplements down to double digit MG. Here is a breakdown of what I needed to weigh and how much of each. I filled #00 gelcaps, for the most part, with the following, using the scale to weigh:12.5MG of Tianeptine Sodium300MG Adrafinil Powder400MG Panax Ginseng Leaf Extract (42+% Gensenosides)600MG Green Tea Extract (50% EGCG, 98% Polyphenols, PE)1000MG Choline L-Bitartrate600MG Phenibut HCLThese are all part of the current Nootropics stack I'm trying, and in particular, I was unable to weigh out anything under 1g accurately with the scale I had. So, I purchased this scale to accurately weight 1mg - 1000mg accurately.***********PERFORMANCE AND QUALITY**************This scale comes with 2 x 10g weights, which are both needed to calibrate the scale. My scale arrived perfectly calibrated, so this was unnecessary. However, at some point I will definitely need to calibrate it since all scales require service at some point, so having the price instruments needed to calibrate is very nice. The scale also came with a nice metal tray for weighing small powders, salts, and supplements out. I found it very convenient. Residue has a tendency to stick to it, but that not the tray's fault.The scan performed with STELLAR accuracy. I opened a couple preweighed gelcaps with ~20-200mg and was able to get an accurate reading down to the mg ever time. It was always spot on.Always make sure you scan is on a perfectly LEVEL, FLAT SURFACE. I can't stress this enough. At first my readings were slightly off, even though the scan was on a flat desk that should have been level. Come to find out the floor was off a couple degrees. When relocating to another surface that was flat AND level (on a level floor) I go consistent, perfect readings.*************Conclusion****************Overall, I'm extremely happy with this scale. I was a bit upset because I selected Saturday delivery, when ordering it on a friday (I needed it ASAP. When the mail came on Saturday and their was no package, I went back to look at the order and the fee for saturday delivery was no where to be found. This is the second time Amazon ignored the fact that saturday delivery was selected (and both times my total had the $8.99 added which I placed the order, and both times the confirmation email had free shipping selected.......) I did, however, receive it the following monday, which is the next business day. The fact that the scale comes with 2 x 10g weights for calibration, a metal tray for weighing powders, as well as some nice tweezers, I think it's well worth the price. I'm very happy and feel I go exactly what I ordered.####******######******Please vote if this review was helpful!!!!! Thanks and have a wonderful day!!!!*******#########*******########
