We all do an amazon search and "Sort by price:low to high" from time to time. This was the least expensive digital device (I don't remember, it may have been the least expensive device overall).  It arrived a few days before a trip.  I knew in advice that my limit was 45 lbs (20 kg).  The scale defaulted to kg, so I was able to get it to work, but switching from kg to lbs took a little finesse.  I figured it all out and the tare setting is wonderful, allowing you to pick the item up, then put is down and reading the "maximum" or "tare" weight. It can be hard to hold 45 lbs at arms link AND read the display.  Overall for the price,it is pretty good.  I ordered another for my father (I wouldn't send him "junk").
