The first unit I received didn't function properly out of the box. The unit button would only switch from the default oz. to lb. oz., then it would read large negative numbers, and pressing any other button would power the unit off. The rest of the time, the display would show gibberish as "numbers" (pretty sure it was aliens), show all of the units as "active", and didn't function at all as a scale.MoreBeer's customer service was great though! As soon as I told them about the issue, they promptly shipped a replacement unit out free of charge. The replacement works perfectly, as advertised. The reviews of this scale seem pretty positive, so maybe mine was the anomaly.The size of the weighing platform is great for being able to measure out grains in a large enough container. The working unit is great for the price and I've had no issues with it.
