Review on 🌡️ ECOWITT Temperature Humidity Particle Detection: Advanced Monitoring Technology for Optimal Indoor Environments by Darryel Tokarczyk

Love the features. He does what he says. What I hate is hearing the fan spin every 30 seconds. Hearing this lets me know it will need service nearing the end of the warranty and possibly a new fan. For the price it's disappointing. It's not LOUD, but it's not quiet either. If the fan was always on, I would never notice the fan spinning, which is distracting. I can move it away from my ears, but that interferes with my aim of observing my immediate surroundings. At that point someone told you about it lol. It is very convenient with 5 measurements in 1 box.
