I'll jump in with the pros and the cons. There will be some overlap.
Pros:
- A cost effective solution for knowing the temperature and humidity level. Considering you get six of these guys, it's an amazing buy.
- Small and compact measuring approximately 1.875 by 1.25 inches. Numbers are easy to read with the humidity number being displayed most prominently.
- Fairly accurate. Measuring them against each other on my desktop, all read between 68.7 and 69.4 degrees F with humidity registering 36-38 percent with one showing 36, three displaying 37 and two showing 38. I'd note I do have a small heater running at one end of my desk, so this to me falls into the fairly accurate for the price category.
Cons:
- No way to calibrate.
- These were designed to clip into something, though I don't know what. There are clips on the sides of the units.
- While they are free standing, there is no way to set them at an angle.
- They do feel pretty cheap, so durability and battery life are questions I can't currently address.
Recommendation? Yes, I think I would recommend them for simple, basic information. I intend to put a few of them into my seed starter trays to keep an eye on humidity and temperature when I start my plants, so who knows how they'll do in that warm, humid environment. But I'd order them again given my overall first impressions.
