### ⭐⭐⭐⭐⭐ Well made and acurate.
*by M***S on 18 September 2025*

Acurate, well the temperature is part is. I have no way to test how acurate the sound level part is but as the thermometer side is within a tenth of a degree C the sound side is likely to follow as the whole meter is sftware calibrated.

### ⭐⭐⭐⭐⭐ Very happy.
*by A***R on 14 December 2025*

Very useful gadget. Having temperature and humidity also is a nice feature.

### ⭐⭐⭐⭐ fantastic functionality but there is one problem
*by M***K on 14 April 2025*

I give it 5 stars for functionality. It has exactly everything you need. It has ideal dimensions and is comfortable. I didn't have the opportunity to check the calibration but comparing the results I think it is very accurate for not profesional measurements. Unfortunately, there is one prolem, the body is delicate. When the meter is lying on the desk and no one touches it, it works properly. But just pick it up and parts of the screen disappear. Maybe it's just this one. I decided to return it. BTW it's not that easy because there is no option to print a sticker and the QR code usually doesn't work and you waste a lot of time.
