I don't even think it was off by an ounce. Perfect for our trip the the DR where we had to checked a bag (My boyfriend is a major over-packer) and subsequent trip to Florida (I did a lot of shopping and needed to make sure I didn't end up over-weight on the way back). I love this thing. Easy to use once I figured out how to set it to lbs. nice and small so it fits nicely into a corner of my carry on bag.
