Accuteck All-In-One Series W-8250-50BS A-PT 50 Digital with AC Adapter (Silver)

If you sell online and need an accurate postal scale, this is the one you want! I no longer sell online but when I ship packages to family and friends I still print the labels from home. I used this scale for 15 years, and it finally bit the dust. So I ordered the same one again, any time you can get 15 years of use from a product these days you stay with it! I never used the battery, always just plugged it in so I can not speak to battery life. It is so accurate you will never have to worry if you've got the right weight! Don't let the size fool you, you can still put large boxes on it and it is still accurate, to see the weight with large boxes you push the HOLD button on the side, remove the box and it will keep the weight in the window until you push the HOLD button again. It says up to 30 pounds, but I have actually gotten accurate weight up to 40 pounds. Buy it! It's a little work horse and you won't be disappointed!
