Review on 🌡️ Continuous Temperature Monitoring with Relative Humidity Integration by Kenny Sarma

Purchased in July 2015. It was working fine until January of this year (about half a year) and then here's what happened: the LCD stopped showing the lower half of each digit (although the readings could still be deciphered - hardly - with some guesswork), but within the next week the device stopped working spontaneously at short intervals (hung and stopped monitoring) and could only be revived by a reset. Now it barely works and only for very short periods of time. Because I need it to constantly monitor the air quality around me - and most importantly to sound the alarm when CO2 levels are too high - to have a device that works only intermittently and maybe only 10% of the time is working. when it's on and its readings are barely distinguishable doesn't help me. Well I may have received an unusual defective unit but if your health depends on a monitor like this I would definitely think twice because for me $130 was down the drain and a health hazard before I realized it. didn't work. I note that Revain has taken care of the fulfillment (so you don't have to wait anymore to ship overseas, I think from China, and this might also lead to better quality control - at least for devices sold by Revain - but then again, I think you're taking a risk (financially, at least) However, if it works, then it was right.
