As a seller on ebay I grew tired of estimating how much an item weighed and then loosing money on postage fees collected because I guessed on the weight. Many times I would have to pay more to ship a package than what I had quoted in my auction. That grew old very fast.
I found this little 5 lb. digital scale on sale at Office Max and since the majority of my sales are under that weight, I picked this one. It is very light and easy to take from room to room, wherever I am packaging and have a flat even space, usually the kitchen counter. The screen is bright and the numbers are easy to read. The scale shuts off by itself after a half minute or so, no need to worry about running out the batteries.
Before I list an item on ebay now, I take the item and place it in a shipping box and weigh it. I can quote almost to the penny what it would cost to ship an item media rate, first class or prioirty. I can input this information into the paypal shipping program and it prints out my postage label.
This scale is one of the best investments I have made and it has worked flawlessly since the day I purchased it 3 years ago. It gets my recommendation.
