## Before you buy

- The listing gives conflicting temperature accuracy figures: the details field says 1 °C, while the feature text says +/-2ºF. The display is described as 4.5 inches in the title and 4.5 inch in feature copy. Confirm the accuracy claim and included sensor count for the selected listing. Battery quantity and type are not specified. USB is listed as connectivity despite wireless sensors being described. The product is claimed to include three outdoor sensors and a USB cable, while the explicit included-components field names only an instruction manual. Check the selected listing for the kit contents. The one-year warranty is a listing claim, with no coverage terms supplied.

## In the box

- User manual (Included)
- Three outdoor sensors (Check selected pack): Claimed in feature text, but absent from the explicit included-components field.
- USB cable (Check selected pack): Claimed in feature text, but absent from the explicit included-components field.

## A good fit for

- People who want to view indoor and outdoor temperature and humidity across three sensor locations.
- Households, gardens, or offices that can use local display alerts and daily high/low records.
- Buyers who want a display that can run its backlight continuously when connected to USB.

## Less suited to

- People who need a clearly established accuracy specification before purchase.
- Buyers who require confirmed battery details or guaranteed sensor reliability.

## Customer feedback

Customer feedback describes setup as easy and often praises readability and perceived accuracy. Some customers say sensors connect quickly, while others report connectivity problems. Battery life receives mixed comments, including concern about the number of batteries needed, and reliability criticism includes reports of sensors failing within six months. For buyers using all three sensor locations, the reported connection and reliability concerns matter alongside the claimed 30-second updates and broad transmission range. These are customer reports, not verified product tests.
- Positive themes: Customer feedback often praises ease of setup, readability, and perceived accuracy.
- Negative themes: Some customers report sensor failures within six months.
- Mixed feedback: Customers describe connectivity as mixed, with some reporting quick pairing and others experiencing connection problems.
- Mixed feedback: Battery-life feedback is mixed, including comments that the device needs many batteries.

## Frequently asked questions

### Can the display show readings from three sensors?
The listing says it displays data from three sensors and describes three outdoor sensors in its kit claim. The explicit included-components field lists only an instruction manual, so confirm the selected listing's package contents.
### Does the backlight stay on continuously?
The listing says USB power keeps the backlight on and offers three brightness settings. It does not state that battery power provides the same always-on behavior.
### What is the stated temperature accuracy?
The information conflicts: one details field gives 1 °C, while the feature description claims +/-2ºF. The accuracy should be treated as unconfirmed.
### How often are readings updated and records reset?
The listing states that readings transmit every 30 seconds and that maximum/minimum records reset automatically every 24 hours.
