What to know before buying

Listing details to confirm

The listing details are inconsistent about the package: a details field lists only the caliper, while feature text claims a ruler, screwdriver, two batteries, and a protective case. Check the selected listing to confirm which accessories are included. The listed measurement range and metric equivalent appear in different formats, so confirm the required range and units before relying on them. The seller also says some battery covers may be screwed during an upgrade testing stage. Loosen the locking screw before use, and take care around the described sharp stainless-steel corners and edges.
