Great scale, overkill for the home, but its sister products look just right.
Positive Product Points
The ultra-fine resolution (+/- 0.1 gram) is awesome for measuring espresso shot quantities. It has a large, easy-to-read display. If you want just the very best of everything and money is no object, put this scale on your list. It has more features than anyone could hope to use in a kitchen scale.
Negative Product Points
It's too expensive to justify (if you pay retail). It's capacity is too small for it to be tremendously useful around the house. It takes a lot of batteries, and wears them down quickly. Initially determining how to switch between ounces and grams was difficult and counter-intuitive.
Detailed Commentary
This particular product is one that nobody in their right mind would buy at retail just to measure coffee, but I thought it merited a review because (a) I have one and use it for coffee-related activity; (b) I think it's features and quality are representative of other Ohaus scales that are more affordable (Ohaus has a compact line that's related to mine that retails around $65), and (c) you never know when you'll come across one used, and this review may be helpful to you in determining how much you're willing to pay.
This scale is a professional laboratory model with numerous features suited to that environment, such as an RS-232 interface so you can download data to a PC, as well as an optional 110V power supply stepped down to some DC input, of course. Fortunately, its incredible functionality does not inhibit its usability (except that a cryptic procedure is required the first time you want to switch from US to SI units). It has a compact form factor and is certainly attractive enough for kitchen use. It also has a removable stainless steel stage which is obviously terrific in the kitchen.
There are many other positives about this unit, as one might expect on a scale that retails in excess of $500. Controls are operated via a membrane panel which is impervious to most cleaners and can be easily and safely wiped down. It has a large, easy-to-read display for those of us with aging eyes. It can be powered via eight AA batteries which makes it very mobile. But best of all, it is deadly accurate and has resolution of a tenth of a gram (+/- 0.1 gram). Variations of as little as half a gram can make a difference in the quality of an espresso shot, so this is a useful attribute, indeed.
On the negative side... price, of course. Frankly, you would have to be crazy to spend $550 on a kitchen scale. But I came across this one cheap, and I'm sure others will, too. I would probably pay up to $100 for this model. It's relatively small capacity is another drawback. While 810 grams is sufficient capacity for most tasks related to roasting or brewing coffee, you might want a scale of this price to be more versatile around the house, for example, weighing packages for shipping, apples for pies, etc. For that you really need a few pounds, at least. I would like the unit better if I didn't have to feed it eight AA's every six weeks or so. Lastly, a truly versatile scale should have a "hold" button so you can place an oversize package on it, have it lock in a measurement, then dispaly the measurement when the package is removed.
Overall, this particular scale is way overkill for home use, but it certainly would cause me to consider other more affordable products by Ohaus for use in the home.
