What to know before buying

Listing details to confirm

The listing is inconsistent about the LCD having three digits in a feature bullet and four digits in the description. It also gives weight as 316 Grams in the details but approximately 129 g in the description, and dimensions as 12.2L x 5.5W centimetres in the details versus approximately 122 x 55 x 26 mm in the description. The stated measurement is variously called accuracy and resolution. Confirm the relevant specification and fit before purchase, especially if weight or mounting dimensions matter. The package description claims a storage case, but no explicit package list was supplied.

Who is it for?

A good fit for

Workshop users checking small linear movement or machine-part tolerances.
Users who want a digital readout with metric/inch conversion and zero setting.
3D printer owners considering Z-axis levelling, as mentioned in customer feedback.

Less suited to

Buyers who need a clearly established weight, digit count or mounting fit without confirming the conflicting listing details.

Customer feedback describes the gauge as well-made and good value, and mentions use for levelling a 3D printer Z axis. Readability and accuracy receive mixed reactions, so buyers relying on repeatable measurements should allow for checking the instrument against their requirements. The listing’s stated 0.01 mm figure is a product claim, not evidence that every customer found it accurate. The aggregate rating is 4.6 out of 5 from 619 ratings, but ratings alone do not explain individual experiences.

Positive themes

Customers describe the gauge as well-made and good value.
Some customers appreciate the digital display and storage case.

Mixed feedback

Accuracy feedback is mixed, including reports that it was not accurate.

Frequently asked questions

What measurement range is stated?

The title and feature text specify 0–12.7 mm, also described as 0–0.5 inch. The details field gives the range as 12.7 without a unit.

Can it display measurements in inches?

The listing says the display can be switched between millimetres and inches.

Does it include a magnetic base?

A magnetic base is not listed as included. The listing describes a removable rear cover that can be used with a different magnetic-base holder.

What do customers report about accuracy and readability?

Customer feedback is mixed on both. Some find the display easier to read, while others report accuracy concerns. The listed 0.01 mm figure should not be treated as independently verified performance.
