Pros: Inexpensive
Accurate
Easy to Clean

Cons: Poor battery life
Uses coin cell CR2032 3V battery

Other Thoughts: This is a good inexpensive scale to purchase if you plan to use it occasionally. The scale uses a non-standard coin cell CR2032 3V battery and with daily use it discharges quickly. Tip: when the LCD reads LO (need to replace the battery) GENTLY rock it/bump it continually on the table while pushing the power button until the scale comes ready. By using this method you can get at least a few more days out of the battery. I tested the accuracy after using the bump it method and the scale is still fairly accurate. ~Cheers

Pros: Lightweight, slim profile makes it easy to store. Display is easy to read. Very glad I purchased this.

Cons: None

Pros: Does what it is supposed to do.

Cons: None

Other Thoughts: Recommend this.

Pros: Opening the box, I was surprised at the weight of this scale, and how it has a stainless plate over a solid slab of glass for a platform.

Testing it with a 1.015 kg F2 standard lab calibration weights set, I was surprised that this scale indicated +/-1 gram from 5-1,000 g, more accurate than I expected given the cost (on sale).

I'd almost rate this scale a 4, but for a few too many minor issues noted below.

Out of the box center of platform calibration was pretty good, and needed no adjustment (not possible anyway on this), unlike my higher precision lab scales, but beware of issues noted below.

Cons: That calibration accuracy didn't hold up when tested for linearity around the platform. Using a 350 g object ~30 mm around, one corner indicated the same as with test weights in the center. Its opposite diagonal read +2g. The other two corners read +6 and -6 grams, or a 12 gram potential variation on two diagonal opposite corners based on where the test object is placed.

Notably, the spec's on Rosewill or NewEgg product pages list display resolution, and make no claims of accuracy. Still, degrading by more than a factor of 10 from pretty good center of plate calibration to two corners is disappointing.

There is no apparent or manual listed calibration mode as many scales include.

As spec'd, there's an easy gram-ounce choice, but no pounds-ounces or other modes.

While the stainless over glass plate feels solid, it appears there are edges where the metal is cut out around the display and switches, and at the edges, where liquids or small particles could be trapped and difficult to clean. That might make this scale illegal to use in commercial kitchens, even for cooking (and not just "trade" calibration uses).

Other Thoughts: This scale has a "hold" mode, as hinted on the display at power on, but it's momentary holding the "On/tare" button for a short period, not so long as to turn the scale off, and not retained as hold once the finger is removed.

Unlike many scales, the controls on this are touch sensors in the glass measurement plate, and so do change weighed amount. The "hold" mode operates fast enough that I saw little indication shift.

It'd be nice to have a "stay on" mode, which some digital scales have if some button press mode is used. This one doesn't claim more than 60 seconds on since last operation, and doesn't have an obvious such function either (trying both buttons, long or double presses, etc).

I have other strain gauge based scales with ranges from 1 mg to 136 kg and up to 50,000:1 range, but was missing one in this range. In many respects this is a nice scale, but it does have a few quirks and limits. I would not buy it absent one of NewEgg's deep discount sales, and would seek better position linearity, and common industrial features of count, calibration, and added units choices, for full price on this model.

Also of note, while the NewEgg/Rosewill pictures of this scale are accurate, the listed size appears to be that of the box, not the scale. The scale itself is smaller, around 15 mm thick, and 143 mm wide, 200 mm deep.

Just out of curiosity, since I used testing this new scale to verify calibration on two of my high precision scales at the same time, I pulled out a 2 lb. Pellouze postal scale, and an old Chatillion 25 lb spring scale that was my grandmother's kitchen scale from back when my (deceased) mother was a kid. The former read 0.3 to 0.5 oz high for most of its range. The latter I'd restored a bit around 15 years ago, and while it's nowhere near the precision of these new generation cheap digital scales, it read exactly 2 pounds as closely as can be read, when I placed 910 grams of calibration weights on it.

Pros: $9.99 price and if wanted fancy paper weight this is scale to buy!!!!

Cons: will not weigh anything accurate even if get it to weigh at all.can of soup is 2 grams a bottle of pop said 4grams and that's after trying like 10 times turning off-on.total junk and newegg should stop selling it if they do not want to lose more custormers.i have learned now never to buy anything like this from them again since if I want to return I pay.if I want replacement I pay and 99% chance just be junk again.never again will I buy from newegg stuff like this unless they start paying return shipping charges.

Other Thoughts: don't be fooled by price = it is junk

Pros: Use this to weigh my bike parts and everything! Works fine.

Cons: None

Pros: nice looking

Cons: only shows oz, can't automatically convert to lb

Pros: .05 ounces is really nice if you are trying to get that recipe exact. A bit overkill but did come in handy once in a while. My old one was in 1/2 ozs.
It remembers your last unit setting (oz/gram) so you don't have to change it all the time.
Auto power off after set time.

Cons: The tare and units buttons are a bit sensitive. Changing from grams to oz sometimes double toggles and thus stays as grams.

Other Thoughts: Wife thinks it's hard to turn off, I think she's just not used to holding the off button for 3 seconds to turn off tablets/scales etc. Her laptop reacts with a tap of the button, thus everything else should. :-)
