Reed Instruments R5090 Power Meter

The REED Instruments R5090 Power Meter has garnered mixed feedback from customers, revealing both strengths and weaknesses in its design and functionality. On a positive note, many users commend its accuracy and the array of features it offers, including the ability to monitor current, wattage, voltage, frequency, and even cost calculations. The device is noted for its robust build quality, suggesting that it is made to last compared to other brands in the market. However, it is not without its drawbacks. A recurring theme among reviewers is the lack of a backlit display, which many customers found frustrating as it makes the screen difficult to read in low light conditions. This is perceived as a significant oversight, especially for a device in this price range. Furthermore, reliability issues have emerged, particularly regarding the battery—the product's reliance on a CR2032 battery means that if the battery fails, it renders the device inoperable, even when connected to a wall outlet. This has raised concerns about its overall design and usability. Despite these issues, the R5090 is praised for its performance and functionality, but potential buyers should weigh the advantages against the Considered drawbacks, particularly the display and battery-related concerns. **
