## Before you buy

- Listing details conflict on weight: the product details list 145 g, while the detailed specification text says Approximately 0.49lb \(223g\). The title says 4000 counts, while the detailed specification describes a 3999-count display. Confirm which weight and count convention apply to the offered version. The instruction manual is a reported customer concern.

## In the box

- 1 (Included): The listing gives an explicit included-components value of 1, without identifying the component.

## A good fit for

- DIY users and hobbyists troubleshooting household or automotive electrical issues.
- Buyers seeking a handheld meter with voltage, current, resistance, continuity and additional component measurements.

## Less suited to

- Buyers who need confirmed weight or count details before purchase, since listing specifications differ.
- Users who need a clearly documented instruction manual, given the reported dissatisfaction with it.

## Customer feedback

Customer feedback reports that the meter is easy to use and appreciated for its readings and household troubleshooting. Those impressions fit the listed auto-ranging operation, data hold and range of measurement functions, though they do not establish measurement performance. The instruction manual is a stated concern, which may matter to first-time users. Aggregate ratings are mostly five-star, but a smaller one-star portion shows that experiences are not uniformly positive.
- Positive themes: Customers describe the meter as easy to use and useful for home tasks.
- Positive themes: Customers report satisfaction with its readings and troubleshooting capability.
- Negative themes: Customers express dissatisfaction with the instruction manual.

## Frequently asked questions

### Does this meter use True RMS?
The listing claims True RMS measurement for AC current and voltage.
### What measurements does it support?
The listing describes AC/DC voltage and current, resistance, continuity, capacitance, frequency, temperature and diode testing. It also lists duty cycle and data hold.
### Does the meter select ranges automatically?
Yes. The detailed specifications state auto or manual range selection.
### What should I know about the listed count and weight?
The title says 4000 counts, but the detailed specifications give a 3999-count display. Product details list 145 g, while the specification text says approximately 0.49 lb \(223 g\). Check the offered version if these details matter.
