Pros and cons

Pros

Three selectable unit formats and four measurement modes cover common workshop, craft and household measuring tasks.
Rechargeable operation avoids routine disposable-battery changes, according to the listing.
The claimed 6-inch range and 0.01-millimetre graduation interval provide fine displayed increments within the stated range.

Frequently asked questions

Is the display backlit?

No. The listing identifies it as an orange non-backlit display, so it does not provide its own illumination.

Which measurement units and modes are listed?

It switches between inch, millimetre and fraction formats, and lists inside, outside, depth and step measurement modes.

What charging and runtime does the listing claim?

It claims Type-C charging to full in 20 minutes and four months of use, alongside an auto-off function. The usage conditions for that runtime are not specified.

How should I interpret the accuracy figure?

The listed accuracy is ±0.02 mm/0.001", but it is a manufacturer claim. Customer feedback describes accuracy experiences as mixed, so verify readings for precision-critical work.
