Before - I used to check my weight and then pick up the suitcase and reweigh myself to figure out the suitcase weight.
After - Read lot of reviews online and from consumer reports, and decided to take a chance on this one.  Wow, it works.  Weight displayed is not off my more than 0.3 pounds when verified at airport scales.  I went ahead and ordered 2 more for my family and I would highly recommend this product to anyone who has been bit by the baggage fees!  Goodbye guessing games and excessive fees!!!
