Same as the Post Office 
2008-06-27
This is the same model that the post office would sell you - only for $10.00 more!
Lasts only a few months!

I bought this scale in January... by May it was already giving erroneous weights... turn it on, it gives you a reading of 2oz, now 2.1, now 1.5 hmmm... there is nothing on it! Turn it off and start again... maybe by the tenth time it will read 0 so you can actually weigh your item... Hitting tare doesn't help either.
Very bad quality!
Much Better Than Mechanical Scale! 
2008-06-21
My wife has many craft hobbies and likes to sell things on EBay and other internet forums. This scale is perfect and much easier to use than a mechanical scale. Granted, it is more expensive than a mechanical scale, but you will be far less likely to make postage errors.
As long as you don't need to weigh something that is more than 5 lbs, this scale is perfect.
Excellent scale for small packages 
2008-02-18
I mail a lot of small packages that weight in the range of 3 to 10 ounces. I usually cannot get to the post office during their regular business hours. Therefore, I need an accurate scale to determine postage so I can put the packages in a mail box. I bought a different scale on eBay for about $20. That scale died after about a week. Rather than waste more money, I decided to buy this regulation postal scale from Amazon. I figured that if it died, at least Amazon is great about returns so I wouldn't be out more money. I have had this scale for several weeks now, and it works like a charm. It is accurate to one-tenth of an ounce. I keep it plugged in with the included AC power source, so I cannot comment on battery life. I would highly recommend this scale to anyone who needs to accurately weigh small packages.
The Postal Scale 
2007-12-28
when I first hooked up the scale it only registered in grams and kilos, not ounces and pounds. I emailed the company and they did not respond for 2 weeks. Very unprofessional to me. In the interim I figured it out and the scale works fine except that when standing for a while (plugged in) it will resister 1 or 2 ounces with nothing on it. I'm thinking of getting another one directly from the post office. Allan Palmer
