Pros: inexpensive, reviews show it to be very accurate
Cons: A lot of Harbor Freight items are poor quality
The big reason for buying this scale was the price. I probably bought it on sale for between $12-15. It was the cheapest digital scale I could find. The reviews from others on their site shows that the device is rather accurate. Other digital scales were much more expensive, and for the limited use it will see, I would rather have something inexpensive that's remotely accurate. The fact that it can run on AC or DC and has the AC adapter included made this a real bargain.
Harbor Freight certainly sells some items of questionable quality, but this seems to be one of the great finds in their store.
