The Tally Pro Precision Scale is Fellow's coffee scale built around a stated "Brew Assist" mode that guides the pour toward a coffee-to-water ratio chosen ahead of time. It also has a Timer Mode that shows a stopwatch alongside the weight in grams, plus a general Weight Mode for grams, ounces, pounds and millilitres.
The stated resolution is 0.1 g, with a stated maximum load of 2,500 g (5.5 lbs), beyond which the manufacturer warns the device may be damaged. The manufacturer states the scale is "water resistant" but not waterproof, specifying it should never be immersed in water or other liquids or run through a dishwasher; the weigh pan is removable for cleaning.
Power comes from a rechargeable lithium battery, stated to last 13 hours of continuous use, charged via a 5V, 1A USB-C input; the manufacturer states a charge time of 1-2 hours. Stated dimensions are 177 x 150 x 33 mm (length x width x height per the manufacturer's own labelling) for a weight of 553.5 g. The manufacturer does not state a flow-rate reading feature on the product page.
