### **Cons**
1. **Limited Accuracy** Like many budget-friendly devices, the Doquas HM1-2 may not offer high precision. Temperature and humidity readings could have slight deviations compared to professional-grade meters.
2. **No Data Logging or Connectivity** Unlike smart thermohygrometers, this device does not store historical data or connect to apps for remote monitoring. Users must manually record readings.
3. **Basic Construction** The build quality appears functional but not premium. Some users may find the plastic casing less durable over time, especially if exposed to moisture or rough handling.
4. **No Additional Sensors** It lacks features like air quality (CO , VOCs), barometric pressure, or sleep mode, which could be valuable for comprehensive environmental monitoring.
5. **Potential Calibration Issues** Cheaper devices may require occasional calibration to ensure accuracy, which adds maintenance effort.
6. **Limited Range of Use** While suitable for indoor environments, it may not be ideal for outdoor, industrial, or scientific applications where higher precision is required.
7. **No Backlight or Auto-Shutoff** The display lacks a backlight, which can be inconvenient in low-light conditions, and there s no power-saving feature to extend battery life.

### **Conclusion**
The **Doquas HM1-2 Humidity Meter Pack Thermometer** is a practical choice for users who need a no-frills, low-cost solution for basic temperature and humidity monitoring. It excels in affordability, portability, and simplicity but falls short in terms of advanced features, long-term durability, and precision. If your primary goal is casual or occasional monitoring such as checking humidity levels in a home office, greenhouse, or storage space this device can fulfill its purpose adequately. However, if you require detailed data, smart connectivity, or higher accuracy, investing in a more advanced model may be worthwhile.
