---

1. **Limited Built-in Display** Unlike some standalone flow meters, this unit does not have a built-in digital display, requiring an external gauge or data logging system for real-time readings.

2. **Requires Additional Hardware** To fully utilize its features, you may need to purchase additional sensors, wiring harnesses, or display interfaces, increasing the overall cost.

3. **Learning Curve for Setup** Proper calibration and integration with an ECU or data logger may require technical knowledge, especially for beginners.

4. **Potential Signal Noise in Noisy Environments** In high-vibration or electrically noisy environments (e.g., near ignition systems), the analog or digital signals may require filtering or shielding.

5. **Not a Standalone Solution** Unlike a complete flow meter unit with a built-in display, this is a monitoring module that needs to be paired with other components for full functionality.

6. **Limited Brand Support** Depending on the manufacturer, customer support and availability of spare parts may be limited compared to more established brands.

7. **Cost of Accessories** While the unit itself is reasonably priced, the total cost of a complete system (including sensors, wiring, and display) may be higher than expected.

8. **Compatibility with Older Systems** Some older vehicles or non-automotive applications may require additional adapters or modifications to integrate the GM-1-DC-R12 properly.

9. **Potential for Overkill in Simple Applications** If you only need basic flow monitoring without advanced tuning or logging, a simpler, less expensive solution (e.g., a basic analog gauge) might suffice.

10. **Risk of Incorrect Installation Leading to Damage** Improper wiring or sensor placement can damage the unit or provide inaccurate readings, so careful installation is essential.
