By Brett H HALL OF FAMETOP 10 REVIEWER on July 29 2014
I have an ongoing use for an accurate portable scale suitable for small items. We tend to visit our local auction on a weekly basis and my wife has a liking for jewellery which can be an outstanding bargain there. However, the majority of bidders are professionals who are interested in the scrap value of the items in the auction, rather than any aesthetic appeal, and bid accordingly so as to make a profit. It is hugely helpful to be able to assess the scrap value of items and pitch bids accordingly. This item is perfect for the job.

These scales are a convenient size being approximately 4.0 inches by 3.5 inches by an inch, and can easily be carried in my wife's handbag. As far as accuracy is concerned, when I tested these against the two 10 gram weights supplied, they came in at about 0.02 of a gram heavy. This level of accuracy is fine for my purposes. However, I then used the recalibration method described in the instructions which was very simple and took all of about 30 seconds and they then measured within 0.002 of a gram of the supplied weights.

The scales are only suitable for relatively small items as the range is up to 20 grams or roughly 0.7 of an ounce. As a guide a ring would typically weigh about 3 grams. They take two AAA batteries which are supplied and easily replaced with a clip-on cover at the back. The unit turns itself off after a short period of non use to preserve battery life. Alternative measurements are in carats, grains, OZT or DWT.

I was very impressed with this set of scales which was exactly what I was looking for. Smart Weigh are very good at manufacturing this sort of precision item - this is the second very small digital scale of theirs which I have reviewed and I have had no significant criticism of either.

Decent scale for the price, but it does have some problems, namely that it's very inaccurate when weighing anything under 10mg. Also the displayed weight begins to constantly decrease after a few seconds of turning it on. Would not recommend this scale if you need accuracy under the 10mg range, but otherwise it works well.

This precision scale arrived in my mail box about two days after I ordered it. Fast shipping! It was like minus 5 outside, so I let it stand for 45 minutes or so. Then I got it calibrated in no time, following clearly stated instructions in the accompanying booklet. Tried the 10 g calibrating weight, and then added the other 10 g weight and it registered 21 g. I redid the weighing a few times and it always registered 20 g plus or minus 2 mg. Impressive! Then I started to weigh things around. Did you know that a red pepper kernel weighs about one third of a black pepper kernel, which is about 75 mg? Now, this is very heavy compared to a piece of paper the size of your fingernail, which weighs about 5 mg. In my opinion, this is very nice precision. From now on, I sure can control my diet. Especially since I'm fully satisfied!

It's perfect, reliable and easy to use. The price is excellent and the shipping didn't take too long. I would recommend this item to whoever requires to precisely measure in oz ,grams, carats, or about any kind of measurement for jewellery.

This scale is extremely small, about the size of an average hand, could easily fit in a back pocket or in a hoody pocket.

This scale has some aestetics, but if you are not looking for the precision buy the ACC200 Accustar pocket scale which is even smaller and has a bigger surface area to place your measuring goods!

Pros:

Extremely accurate up to 0.001g!
Batteries included (rare these days)
2 x 10g weights to see precision of this little machine!
Small
Practically weightless
Easy to read
Tweezers
Cheap, good price

Cons:
Pretty much none!

Bought this for reloading and wish i had spent a bit more. the tray is not the same as the picture. It is a little pan that sits on a dime sized pad. The pan is not big enough to hold all the powder so i have to balance my powder pan on top of the supplied pan bacuse the dime sized plate is recessed and my powder tray does not touch it. Also found inconsistent repeatability as now and then i have to rezero this scale after removing my powder pan. if it came like the picture it would be better. May be completely adequate for other purposes.

i have no experience with trying to weight 1 or even 10 milligrams. I could never get this at 0.000. Thought it would be easier.
Guess not.

I got this scale for the sole purpose of weighing items less than 10mg, but this scale does not. If I keep adding light object to it, the weight will not change at all until suddenly it changes for like .016 or .022. It is quite accurate in all measurements high than that. But I already have a scale that does that.... I wanted this one for the extra decimal place, but it seems kind of pointless
