In my small business I needed to weigh medium to large items and boxes on a floor scale for shipping. Rather than pay way too much for an industrial model, I used a digital bathroom scale. I found it to be close enough for the rough accuracy I required when over 15lbs (7kg), as well it measures up to 330lbs (150kg). Way more than I can lift.

I was frustrated because the display was always hidden under the item I weighed. Sure the result locked in but only if you got lucky, blindly timing it right and quickly moving the box after.
