What to know before buying

Listing details to confirm

The listing is inconsistent about supported current and resolution: the product title and specifications list 600 A AC/DC, feature copy explicitly describes AC current up to 600 A, and another manufacturer section claims AC/DC 600 A with 0.01 A high resolution. The provided customer summary also reports a 0.1 A DC measurement. Confirm the measurement ranges and resolution needed for your work before buying.

Customer feedback highlights the compact size, portability, thin jaw and usefulness for automotive work. The supplied summary also reports positive impressions of accuracy and versatility, including AC and DC current use. These perceptions fit the listed pocket-sized dimensions and broad function set, but customer comments do not resolve the listing's conflicting details about current range and resolution. Aggregate ratings skew strongly toward five stars, though they do not explain the lower ratings.
