This was a test purchase as a decision for further purchases. Sorry quality not usable! Bought a usable product in Switzerland for the same price.
Callipers came covered in grime and metal filings. They turned on, which almost pushes the rating to a 2/5 in quality. Outside jaws are not parallel, which results in a difference of 0.34 mm between the tips and the inside of the jaws. Tips are misaligned to the point that a 1 mm wire fits between them when they are closed. Not a single straight line on this instrument. Lots of slack in the sliding jaw, depending on force the reading can vary up to 0.28 mm for the pair I got. Slide can't be adjusted since the brass screw for adjusting tension was split. Moving the slide feels like dragging a grand piano trough a gravel yard. They definitely are not hardened and can be carved with a scalpel blade without any damage to the scalpel. Repeatablility of zero reading (determined as standard deviation between 10 measurements) is 0.01 mm (0.02 0.02 0.010.01 0.03 0.01 0.01 0 0.01 -0.01). Accuracy is very poor: Properly "zeroed", the callipers give me a reading of 149.09 mm against the 150.00 mm of an actual quality instrument. 0.91 mm off at 150 mm is far beyond the specified +/- 0.03 mm. I have disposed of them.
Jamen den har længe undervejs, den første smed "Post uduelig Nord" væk som de så ofte har gjort, men Banggood var heldigvis flinke og sendte en ny, og NU kom den idag d.24 marts. Tak til Banggood
