## Before you buy

- Listing details are inconsistent or unconfirmed: dimensions are also stated as 60×28×20 mm, temperature limits are separately listed as -20℃ to 60℃ and 253.15 Degrees Celsius at the lower end and 140 Degrees Fahrenheit at the upper end, and battery information says both Lithium-Ion and two built-in AAA batteries. Check the selected listing for the applicable dimensions, temperature limits and battery type.

## In the box

- Outdoor Meter (Included)
- User manual (Included)
- 2 built-in AAA batteries (Included): The listing also identifies the battery type as Lithium-Ion, so the battery details are inconsistent.
- Lanyard (Included)

## A good fit for

- People who want temperature and humidity monitoring in a refrigerator, greenhouse, instrument case or other indoor or outdoor space.
- Users who want to export historical readings and can retrieve them over Bluetooth.
- SwitchBot system owners who want Hub-dependent threshold notifications or unlimited cloud storage.

## Less suited to

- Buyers who need remote alerts without a SwitchBot Hub.
- People needing guaranteed Bluetooth coverage through walls or across the full stated distance in obstructed settings.

## Customer feedback

Customer feedback describes the meter as easy to use and portable, with reports of accurate temperature readings and useful tracking of changes over time. That aligns with its compact design and stated data-storage and export functions. Bluetooth experiences are mixed, so buyers relying on readings at the limit of the claimed unobstructed range should consider that feedback. Aggregate ratings are generally favourable but do not establish performance in a particular setup.
- Positive themes: Customers report ease of use, portability and accurate temperature readings, including tracking changes over time.
- Mixed feedback: Bluetooth connectivity receives mixed feedback, with some reporting no problems and others reporting connection issues.

### Can it be used outside?
The listing describes it as IP65 dustproof and waterproof for indoor and outdoor use. Its specific temperature limits differ across listing details, so confirm the applicable range before using it in extreme conditions.
### What batteries does it use?
The package details say two AAA batteries are built in, but another specification describes the battery as Lithium-Ion. Check the selected listing to confirm the battery type.
