I've read the reviews of people who say the scale won't produce repeatable results.  I just repeated the weighing of an empty suitcase 8 times and every time I got 11.6 pounds.  I found that results are not that repeatable unless you use the following procedure:  (1) switch on the scale; (2) press the left button with the hook hanging free; (3) move the scale so that the hook is under the suitcase top handle; (4) lift up very gradually until the suitcase is off the floor; (5) wait until the number settles out; (6) note the reading; (7) SWITCH THE SCALE BACK OFF and repeat.  If you don't follow this procedure, measurements may vary by plus or minus about 0.3 pounds around a mean value.  The whole procedure takes under 15 seconds if you're really slow.

Now let's be real here.  Repeatability doesn't prove accuracy.  A repeatable scale may be repeatably wrong.

I bought this scale to ensure that my bags are under the airlines' 50 pound weight limit.  I've noted that airlines will normally let a bag through if it is within two pounds of 50, so the scale doesn't have to be all that accurate.  In addition, I'd bet the airlines' scales aren't good to better than half a pound, especially considering the beating they take.  My rule of thumb is to stay at or below a reading of 49.2 pounds, just to be safe.  So far, I've run 14 bags through that were just below 50 pounds and I've had no problems.

I couldn't live without this thing now.  When my family travels they like to live on the edge of overweight.  And then they like to buy stuff and bring it home.  I often end up having them switch the high-density items to carry-ons.  We end up switching things around multiple times to get all checked bags under 50.  Before we got this scale, we actually had to switch items on the floor of the airport when we were over the limit.  We were relying on a bathroom scale.  Now we've solved the problem.  It simply wouldn't be possible without this scale.  If you're trying to stay under the airline 50-pound limit, I highly recommend this product.
