perfectly well and well received in good condition.
Very good sound level meter. And in addition with a very clear notice, well done, in several languages. Se which is rare when buying on Aliexpress.
Amazingly fast delivery, very much appreciated. Simply fantastic product from the great Company.
Dear FNIRSI team, I'm really wish you to grow up and to keep your so high levels of customer care.
Thanks and good luck !
it doesn't seem calibrated
at home when it's quiet I get 28 db
talking into the microphone gets me 60-64 which I think it's not that low honestly
sudden noises that are very short sometimes it doesn't pick them up which I needed it for this specifically
decibel X on iPhone seems to be more accurate and supports more sound ranges
many YT reviewrs tested Decobel X app on iPhone sna Android, and saw very good resulst compared to better more exepnsive sound meters than this one.
