What to know before buying

Listing details to confirm

Listing details conflict: the product title and feature text give ±0.001 inches/0.02 mm accuracy across the range, while the specification panel gives ± 0.001 inches/0.02 mm and the detailed accuracy section specifies ±0.03mm/0.001” (>100-200mm). Confirm which accuracy claim applies to your measurements. The title claims two extra button cells and the feature text says three are provided, while the details field says three are required and included. The listed weight of 0.48 Milligrams and dimensions of 9L x 29.8W centimetres appear unusual for a caliper, so confirm those specifications if they matter.

Who is it for?

A good fit for

DIY users and hobbyists measuring components up to 200 mm.
Buyers who want one tool for internal, external, depth and step measurements.
Users who prefer an LCD readout and switching between inch and metric measurements.

Less suited to

Buyers who need an independently verified accuracy specification, especially above 100 mm.
Users who require verified resistance to immersion or heavy water exposure. The listing claims splash protection only.

Customer feedback highlights positive impressions of build quality, construction, display clarity and usefulness at work, and some users appreciate the spare batteries and auto-off. Accuracy and durability experiences are mixed, including reports of early failures. For buyers using the claimed 200 mm range and stated accuracy, these concerns matter most when measurements must remain dependable over time, so treat the listing's accuracy figures as claims rather than verified performance.
