## Before you buy

- Published details are inconsistent: the title claims 4000 counts and True RMS, while the detailed specification lists a 3999 count display and does not explain True RMS. Product dimensions also appear as 16 x 11.5 x 4 centimetres and 145 x 73 x 34 mm, with a separate listing of 16 x 11.51 x 3.99 cm; weight is given as approximately 185 g with battery and elsewhere as 280 g. Confirm the exact model revision, measurement specifications and dimensions for your use. The stated CAT III 600V and CE claims are listing specifications, not independently verified here.

## In the box

- Owner's manual (Included)
- Pair of test leads (Included)
- Pair of alligator clips (Included)
- AstroAI multimeter (Included)
- User manual (Included): Explicit manufacturer contents list; not independently verified.

## A good fit for

- DIY users who need one meter for common AC/DC, resistance, continuity, capacitance, diode and battery checks.
- Buyers who want a backlit display, data hold, kickstand and non-contact voltage detection for troubleshooting.

## Less suited to

- Buyers who require independently verified accuracy, safety compliance or an unambiguous count and True RMS specification before purchase.
- Users needing a measurement function not listed here, such as frequency or temperature.

## Customer feedback

Customer feedback describes the meter as easy to use and versatile for varied circuit-testing tasks, with positive perceptions of functionality, value and reading accuracy. That makes its listed range of common measurements and practical display features relevant to DIY buyers, but comments about accuracy are customer impressions and do not settle the listing's conflicting count and True RMS details. The aggregate ratings are mostly favourable, though a smaller share are lower, so feedback is not uniformly positive.
- Positive themes: Customers report ease of use and useful functionality across different applications.
- Positive themes: Customer feedback describes the product as good value and its readings as close to expectations.

## Frequently asked questions

### What can the AstroAI DM130B measure?
The listing specifies AC/DC voltage and current, resistance, continuity, capacitance, diodes and 1.5, 9 and 12V battery checks.
### Does the DM130B include non-contact voltage detection?
Yes. NCV is listed as a feature for detection near outlets, sockets and terminals. The listing does not provide detailed detection limits.
### How is the meter powered?
It is battery powered. The detailed specification says it uses 3 x 1.5 V AAA batteries, and the product details say three AAA batteries are required.
### Are the count and dimensions consistent across the listing?
No. The title says 4000 counts, while a detailed specification says 3999. Multiple dimension and weight values are also listed, so confirm the exact revision and measurements if they matter.
