Digital Thermometer with External Sensor

When it arrived a day late I was a bit worried but it was fine overall My first impression was that it looks sleek in silver and works well for both inside and outside use As an engineer I appreciate the durability but as a beginner with tech I found it straightforward to use though not perfect I'd recommend it with some reservations because it does what it promises but has minor flaws
- Pros: I was incredibly impressed by how sturdy this thing feels like it can handle getting wet without any issues and the extra sensor lets me check temperatures in different places at once which is super handy for my projects
- Cons: It seemed a bit bulky to carry around and the readings took a moment to stabilize which was annoying when I needed quick checks
