when i first got this, it seemed like a nice little bonus for my workshop. as a builder, i need to monitor conditions to keep materials in good shape, and this does the job fairly well. the packaging was intact when it arrived, which is always a relief. i've only had it for a short while, but it's been reliable so far, giving me accurate readings without any fuss. it's straightforward and does what it claims, which is all i really wanted. i'd recommend it to others looking for a simple way to track temperature and humidity.
- Pros: the display is incredibly clear and easy to read, making it simple to check the temperature and humidity without any strain. the measurements are very accurate, which is great for keeping an eye on things around the house. it runs on common power, so it's flexible and easy to set up wherever needed.
