The quality is bad, the accuracy is worse. But at least they didn't respond to my request for help via email, phone or text. All I had to do was call to tell them their quality had dropped to an all time low. There was a time when a machinist could put a general pocket ruler in his pocket and it was the same ruler he had in his pocket when he retired! This can work well to level a table with a short leg. if you put it under the short leg!
