I too bought mine on eBay. After receiving it I did the salt test calibration. Was unable to get the one I purchased, to calibrate. The adjustment screw would not turn, and was 17% off out of the package.
Would have been a great item if able to calibrate, was well made, easy to read scale but not calibrateable, is the reason I give a 1 star rating.
