Review: Good - Works very well, just have a little bit of bugs on the apps, works fine
Review: Best buy this year. - Spot on! I’m so impressed with X-Sense products. I don’t get the negative reviews about their products as they are quality. I’ve always purchased other brands but no more. This works flawlessly with my current base station. So easy to set up and the temperature and humidity is accurate. The display on my phone is also accurate. I nearly purchased another brand then realised if anything would pair with my current xsense alarm and base station. This is better value for money and now part of the xsense eco system.

### ⭐⭐⭐⭐⭐ Great range from hub, excellent stats and graphs
*by W***N on 28 November 2024*

I have the sensor in my greenhouse which is probably 40m away from the hub through 3 thick walls and it shows with a full signal. The temperature and humidity stats look pretty accurate compared with another sensor I am using for comparison. The graphs in the app are also nicely presented.
