What to know before buying
Listing details to confirm
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.

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.
