Shipping Is a Business of Grams. Every carrier prices in brackets, and every bracket is a cliff. A parcel that weighs 1.02 kg is not a 1 kg parcel, it is a 2 kg parcel, and the difference comes straight out of the margin on a product you already discounted. This scale exists to remove that arithmetic from the realm of hope. It reads from 10 g to 110 lbs (50 kg) with 2 g of resolution, which is fine enough to see the difference between a padded mailer and a padded mailer with a business card inside.
The platform is 10 by 10 inches and 1.7 inches tall, in ABS rather than steel, so it will not rust in a humid stock room and will not scratch a counter. The LCD folds through 90 degrees, which matters more than it sounds: on a low bench you read it flat, on a shelf you fold it up, and you never have to crouch to see whether the number has settled. One button starts the weighing, a tare key zeroes out a container, and a hold key freezes the reading after the parcel comes off the platform so you can write it down or key it into a label. Units switch between kg, lb, lb:oz and g. An overweight alarm fires before you overload the load cell.
Power is deliberately redundant: an AC adapter for a fixed packing bench, and rechargeable cells for the days you carry the scale to a market stall or a courier counter. On battery it can be set to shut down after 1, 3 or 5 minutes of inactivity, which is the difference between a scale that is ready next week and one that is flat. For anyone shipping more than a handful of parcels a week, the scale pays for itself the first time it catches a bracket you would have guessed wrong.
Guess the weight and you price the parcel twice.

Where It Belongs
It belongs wherever a parcel is priced. On a home packing bench for a small brand shipping twenty orders a week, at a courier counter where every gram is billed, at a market stall where the scale travels in a crate and runs on batteries, in a stock room where inbound cartons need to be checked against a supplier invoice, and next to a suitcase the night before a flight when the airline's 23 kg limit suddenly matters. Anywhere the difference between an estimate and an invoice is money, this is the instrument that settles it.
Questions, Answered
Q: How accurate is it really?
A: Resolution is 2 g and the minimum readable weight is 10 g. That is accurate enough for parcel rating and for checking a supplier invoice. It is not a laboratory balance and should not be used for jewellery or precious metals.
Q: Does it come with batteries?
A: No. It ships with an AC adapter and accepts rechargeable cells for portable use. The battery compartment takes standard cells, so replacements are available anywhere.
Q: Can I weigh a box that is bigger than the platform?
A: Yes, as long as the centre of gravity sits over the platform and the box does not rest on the bench. For long parcels, use a piece of board across the platform and tare it first.
Q: What does the hold function do?
A: It freezes the last stable reading after the parcel is removed, so you can write the weight on the box or type it into a label without standing over the display.
Q: Will it weigh a suitcase?
A: Up to 110 lbs (50 kg), which covers any airline allowance. The 10 inch platform takes a standard cabin bag footprint with the bag's weight centred on it.
Q: What happens if I overload it?
A: An overweight alarm sounds before the load cell is damaged. If it does fire, remove the load immediately and let the platform settle; repeated overloading will permanently offset the reading.
