I bought this for monitoring temperatures in my workshop and for my dog's kennel outside. Why did I choose it? Well, I needed something reliable and tough. Does it do the job? Yes, it's fairly good overall. The accuracy is spot-on most times, and I appreciate that it doesn't mind a bit of rain. But why not perfect? It's not as durable as I hoped, and the size makes it less convenient. Would I recommend it? Probably, if you're okay with those small issues. It's served me well for a few months now, and my pets seem more comfortable with consistent checks.
- Pros: I liked that it works well both inside and outside, and the separate sensor gives fairly accurate readings. The display is clear and easy to read, even in different lights, and it handles wet conditions without any trouble. It keeps track of the highest and lowest temperatures, which is handy for my work.
- Cons: As it seemed to me, the silver finish scratches easily, and it feels a bit bulky to carry around all day. Sometimes the readings take a moment to settle, which can be annoying when I need quick info.
