I'm not sure I received counterfeit packaging, but I can't imagine a company like Starrett claiming I did. The vial is clearly off center, the reading changes when you rotate it 180Β° and the bubble disappears entirely unless the window is pointing straight up. This level is highly recommended, which got me confused. Like most things at Revain these days (looking at you Bose) I'll write this off as fake and look elsewhere. Buyers be careful.
