Product Details

Programmable Auto-Off FeatureIf you've ever had your scale turn off on ya in the middle of important measurements, or run out of battery power you'll realize what a blessing this feature is. You can program this gem scale to turn off automatically, or to stay on until ya turn it off yourself.

Protective CaseThis little jewelry scale comes with a hard, protective case to keep your scale, along with all of its accessories, nice and safe.

Bright Backlit DisplayThis digital scale has a fancy backlit display to help ya see your weight readings, even in dim lighting.

Man, This Thing Is Tiny!You won't have to worry about this scale taking up space. It's just over five inches long, and only two and a half inches high.

Hinged Protective WindscreenWhen you're weighing with high precision scales like this one, even the tiniest breeze can interfere with weight readings. This Citizen scale comes with an attached windscreen to keep out those pesky drafts. The protective cover is hinged, ya just lift it up to get it out of the way.

It Remembers The Last Unit Ya UsedIf your application needs weights in the same unit of measurement, (like ounces for instance), it can be a real pain if your scale always turns on ready to weigh in grams. It's a good thing the CB-30 turns on displaying the unit of measurement ya were using when ya turned it off.

Stainless Steel PlatformThe CB-30 has a durable stainless steel weighing platform to make cleanup a breeze. Unlike gold or silver, stainless steel doesn't scratch easily and keeps its shine without rusting or tarnishing.

Easy CalibrationTo make sure ya keep getting the best weight readings from your scale, it helps to calibrate it from time to time. This jewelry scale has instructions to make calibrating your scale easy. The CB30 even comes with the calibration weight ya need to get the job done.

Tare FeatureThe tare button on the front of this digital jewelry scale can be pressed to "zero out" the weight on the scale. You can then add more weight, and the display will only show the weight of the items you're adding. This sure is useful when ya want to use the included expansion tray to weigh your things, or if ya want to get separate weights of multiple items.

Liquid Level IndicatorThis very handy feature will help ya quickly and easily get your scale nice and level. A level scale is important for getting the most accurate weight readings.

Four Useful AccessoriesThe CB-30 comes with great accessories. Use the calibration weight to keep the CB nice and accurate. If you're looking to use the CB-30 as a diamond scale or carat scale, the little expansion bowl is perfect for weighing those teeny tiny jewelry pieces, and ya even get an AC power adapter, just in case ya don't have any batteries on ya. You can store the CB-30, along with the expansion bowl, calibration weight, and adapter in the included protective storage case.

1 YEAR MANUFACTURER'S WARRANTY!Citizen Scales Inc. offers a one year warranty against defects in materials and workmanship. In the rare case ya have a problem with this scale, just give Citizen a call for a repair or replacement.

First, if you're looking for an actual Citizen product, this is not it. I paid what I viewed as a premium price thinking that I was going to get the quality of Citizen. I don't think I got it. The product is from Citizen Scales U.S.A. Judging from the poor English in the manual, like most electronics, I highly doubt it's made in the U.S. So, as best I can tell, it's not "Citizen" and it's not "USA". Perhaps they should just call themselves, "Scales, Inc." Second, the wind screen is very low profile. Great for portability but rendering the scale almost useless for anything but small and medium sized gems (or smaller items/materials). The screen is not removable, so you are stuck with it. Also, the wind screen is too low in profile to accommodate the standard 10g weight that comes with the scale for calibration. Attempting to calibrate with the weight on its side does not seem to work well, so it's a little hit or miss on calibration with the screen propped up, depending on the amount of draft in your space. Perhaps there is a better way to do this (e.g., find a stubby check weight = another purchase). One could probably figure out some of the above by looking closely at the manual. I wish I had - so partly my bad. Third, reliability - I have not used the scale much. Out of the box, I was able to quickly calibrate it and received consistent results for a short period. That was great. Then, inexplicably, results became inconsistent and I was not able to successfully recalibrate the scale for several tries. Later that day, I succeeded in recalibrating, but soon received inconsistent results (actually, this time consistently off by .1 grams, even after multiple, apparently successful recalibrations) with the 10g weight and previously measured (smaller) gems. I was getting ready to ship the balance back to Old Will. But, I'm nothing if not persistent, and still later I was successful in recalibrating and received consistently accurate results. So, for me, the jury is still out on reliability of this scale's accuracy. I expect that some of the consistency issues relate to my lack of experience with this type of balance and the general fiddly nature of any small, portable balance. I have yet to determine to what extent, if any, the product is causing these problems, but it seems likely that it is at least partially culpable. More testing is needed. Fourth, ease of use. The adjustable legs are nice, but they can be inadvertently turned easily. This means that it is very easy to un-align the legs if you are not careful. The level first appeared to be a great idea, but I don't think it's very practical. It seems much more reliable to adjust the legs until the device sits even and completely steady. Slight variation in leg height will cause it to noticeably wobble on a hard surface if checked, and with some fiddling and care not to brush one of the legs out-of-whack, it can be readjusted to level. The process of calibration took a few reads of the manual to decipher, but it's simple and straightforward -- and, it would work better with a check weight that actually fits under the screen. Fifth - overall package. The added items are fine, with the exception of the height of the check weight being too tall, but the case provided does not easily accommodate the package (although it does eventually all fit if you like puzzles) and it has a very "thrown-together" feel that seems more appropriate for a much cheaper product. By comparison, I had a Gemini that was much less expensive and the whole package came together in very well-fitting faux-leather case that gave it a much better feel. After reading many reviews on many scales ranging from US$50 - $500, I feel I have yet to find the holy grail of relatively inexpensive, highly accurate scales. I had hoped that by spending a few extra dollars, this scale would "JUST WORK" (after calibrating). It doesn't - and, I'm not sure if any of them do. Given Citizen Scale USA's somewhat draconian return policy, I bought this thinking of it as a gamble. I don't feel like I lost everything, but I will probably do things differently next time. If my best friend asked me whether to buy from Citizen Scale USA or to buy this scale, at this point, I'd suggest not. But, I wouldn't have a better product to recommend, either. Old Will's was kind enough to send a follow-up email to ask how I liked my purchase. Given the return policy, I haven't bothered (until now) to provide any feedback. I hope this helps. Perhaps the folks at Old Wills will follow up with some helpful suggestions or proposals. We'll see...
