## Before you buy

- The listing gives more than one range description: the details say 0-100%RH and an upper temperature rating of 60 Degrees Celsius, while the product description gives 10% to 99% humidity and -20°C to 60°C. Check the intended measurement range before relying on a boundary reading. Remote range is stated as 80m/260ft with no obstructions, so walls or other obstacles may reduce it. The listing also says the product may arrive branded ThermoPro or TempPro.

## In the box

- 1 x Thermometer Hygrometer (Included)
- User manual (Included)
- 2 x 1.5V AAA batteries (Included)

## A good fit for

- People who want indoor temperature and humidity readings with phone alerts.
- Users who want to review room-condition history and trends in an app.
- Households or workspaces where a clock and simple comfort indicator are useful on the device.

## Less suited to

- Buyers who need a confirmed measurement range at the exact humidity or temperature limits without first resolving the listing's differing range statements.
- Anyone needing an outdoor sensor, since the supplied listing describes indoor monitoring.

## Customer feedback

The supplied evidence contains aggregate ratings but no written customer-feedback summary, so specific praise, complaints or reasons for ratings cannot be established. The rating distribution is mostly five- and four-star, with a smaller spread across lower categories. That offers only a broad indication of mixed customer sentiment and does not confirm the claimed accuracy, app range or alert performance.

## Frequently asked questions

### Can readings be checked on a phone?
The listing claims Bluetooth app access for remote temperature and humidity readings, with a stated range of 80m/260ft in unobstructed conditions.
### Does it send alerts?
The app is described as sending phone notifications when temperature or humidity goes outside ranges set by the user.
### How much history can the app show?
The listing claims historical data views for periods including 24 hours, one week and up to one year.
### What measurement ranges does the listing give?
It gives humidity as both 0-100%RH and 10% to 99%, and temperature as an upper rating of 60 Degrees Celsius and a range of -20°C to 60°C. These details are inconsistent, so confirm the relevant limits before purchase.
