American Weigh Scales BT2 Series Digital Gram Pocket Weight Scale, Stainless-Steel Surface, Backlit LCDBlack, 200 X 0.01G

This is an excellent little scale - I was really surprised how compact it is. I bought it for reloading and for weighing my kids' AWANA Grand Prix/BSA Pinewood Derby cars. After zeroing the scale, the 100g calibration weight weighed in at 100.05 grams. Calibration was very simple and intuitive, and resulted in a perfect, repeatable 100.00 reading. I weighed a piece of deprimed 308 Winchester brass on my sensitive RCBS 505 balance scale (157.2+ grains), then weighed it on the digital scale - they were within .2 grains (0.013 grams) of each other, and the digital scale alternatively measured 157.2 and 157.4. Seeing as the actual weight was really on the strong side of 157.2, I can understand the alternating readings. The scale will weigh up to 200 grams (7.05 ounces, .44 pounds), which is perfect for a 5 ounce max Pinewood Derby car. It was one of the few reasonably priced scales that would measure to the 1/100th of a gram, and use has shown it to be very accurate. For my highly precise rifle reloading it's not *quite* accurate enough (+/- 0.15 grains) to measure powder (that's what the 0.1 grain RCBS scale is for), but for practice rounds it is plenty accurate. I'll be using it for sorting brass and bullets and checking for double loads. Overall, this is an excellent little scale for a great price.

This is an absolutely fantastic scale for its price. I was initially skeptical that such a cheap scale would really have 0.01 gram precision, since equivalent laboratory-grade scales are over $100. I bought a set of calibration weights to test this scale. When I first opened it, it was already nearly perfectly calibrated, only off by 0.01-0.02 g. The scale is really easy to recalibrate, and after recalibration it only varied by 0.00-0.01 g (I am suspicious that my calibration weights are less accurately massed than this scale, which seems perfect). I am also impressed by the balance of the weighing platform. Putting a sample anywhere on the platform, even just on one corner, yields the exact same reading. The scale is sleek and small, and comes in a nice little pouch in a nice little box. The lid of the scale is easily removable, and you can tare the scale to zero using the lid as a weighing tray for larger objects. Again, repeated measurements of the same sample give the exact same readings. The inside of the lid contains clear, detailed instructions for taring and recalibration. The previous reviews of this product are correct - the touchscreen looks a little cheaply made, but it works exceptionally well. The battery spaces do seem to be a little large, so the batteries may wiggle, but it hasn't created any problems for me, so I haven't had to fix anything. Batteries are included. I bought this product for scientific research (I'm a student, the $100+ laboratory-grade scales are out of my price range), and I use it to weigh very small fossils and rocks. I am absolutely thrilled with the accuracy, precision, small size, and ease of use of this very cheap but quality scale.

First, this little guy requires a 100g or 200g calibration weight - if you want to calibrate it. So don't buy a 50g like I did. ;) Oops. Now you know the competence of this operator/reviewer. Second, the patriotic side of me chose this over the competition because it's an "American Weigh Scales" product. "Keep jobs in America", thought I. "Don't import another piece of rubbish." Well, it's not rubbish, but in big bold letters on the case: "MADE IN CHINA". Oops. So much for keeping jobs in America. That said, I have nothing against Chinese products, so groovy. Was just half-trying to do my patriotic duty. I bought this because I'd like some precision in my scale - 1/100th of a gram scale for under $20!? Great! Well, yeah, but... If you REQUIRE precision, this one may not be the best bet (HUGE surprise, it's under $20.) Oh well. Even weighing the calibration weight leads to incorrect readings every time. Put the weight on, calibrate, 100g. Take the weight off, 0g. "Perfect!" Repeat experiment, no calibration. Put weight on, "100.03g". Take weight off, "0.02g". Oh. Hmph. So, it's not brilliant, nor should it be for the price, but it's not terrible. I suppose it will do. =) But if you want to keep jobs in America, better to spend $70 for one that really works precisely well. + Light, seemingly durable, compact, works okay - Cheap build quality and feel, works okay Overall, much as expected. Just hoped it'd worked a little better than it does. Definitely not terrible, I'd even venture good - considering the price!

La meilleure balance que j’ai eu !!
