I don't know how accurate it is, I don't have a comparison with it but so far it seems good. I use it to level a 3D printer table and it seems perfect for that. I don't know how long it will last, I'm pretty gentle with it, but I know some of them have flaws. It's all metal with a grommet on the back for fastening (which I don't need but good for the future). Comes in a styrofoam clamshell with a card sleeve to keep it together. Perhaps the price saving compared to other indicators is due to the storage situation.
