Ansxiy Postal Scale, small & portable analog weight detection devic

Perfect for letters and for darts! It's graduated on one side in ounces and the other side in grams. One of the first things I noticed is how the resolution and sensitivity are more precise for smaller weights than for heavier weights. That's a unique feature from how the counterweight gradually moves from nearly vertical for light objects to nearly horizontal for heavy ones, and enables weighing things from just a couple of grams to 100 grams while maintaining accuracy of a few percent, which might be ±1 gram for smaller objects, or ±5 grams for heavier things. How practical! I compared the accuracy for several objects from around half an ounce or 15 grams, up to 50 grams (nearly 2 oz). For each thing I weighed, I checked the weight on my much nicer triple beam balance, and this little handheld scale was accurate within the precision I could read it. Without having tested it, I wouldn't have trusted it as much. It has a little friction in it, so you can weigh the same object and get the scale to read a range of numbers (a dart that weighs 22 grams could read anywhere from 20-24), but you can fool with it for a couple of seconds and get an idea of when you're in the middle of the range that friction will allow it to stop at. And once you're there, mine is reading the same value that my good scale does. Using this, I will have confidence when I send a letter whether I need to add a second stamp. If I have a bulky envelope, I'll clip it to this sucker. If it's over an ounce or very close, I'll add a second stamp and call it good. No mail returned to sender for insufficient postage, and no guessing and wasting unnecessary stamps. And like I said, it's also a fun thing to have on hand if you meet friends to throw darts, and portable enough to bring along.

Tired of adding that extra stamp just to make sure that someone doesn't get charged for insufficient postage? At current prices, this device pays for itself in just a few letters. This is basic simplicity that is perfect for occasional use. Not appropriate for volume shippers, however.

It's fairly accurate. Not as accurate as a digital scale obviously, but does the job when in a pinch or out about nonetheless. I don't recommend actually putting it on a key chain with other stuff and/or putting it in your pocket as it can throw off the measurements a bit

Light and great scale.

These are great. Very accurate and they gave me 2 of them! I was expecting only one. Im very happy with this order. The price is dirt cheap, the product is great and works well, and the shipping was fast.
