## Review summary

Overall, Fuel-It! ECA is valued for its UI and hardware integration, but recurring issues with Bluetooth reliability, sliders and blending calculator accuracy, removal of auto lock screen, and stability problems undermine its consistency. Users want more precise input options, a fix for pairing and channel selection, and continued updates to improve reliability.

### Pros

- Works as advertised and fulfills its core purpose of monitoring ethanol content and guiding mixing.
- Quick and reliable Bluetooth connection when it works.
- Useful features such as the ethanol blend calculator and fuel temperature display.
- Clean GUI with a visually appealing interface.
- Beneficial updates and ongoing improvements that add needed functionality.

### Cons

- Bluetooth connectivity is inconsistent with pairing failures and sometimes forces closes, with no option to change the module channel.
- Sliders and input controls are hard to use and basis calculations for blends can be inaccurate, requiring manual adjustments.
- Irregular or inaccurate ethanol blending calculations for blended fuels and tank size inputs that restrict decimals.
- Auto Lock Screen feature has been removed, requiring users to keep the screen on manually or rely on the phone settings.
- App crashes or becomes unstable at times and user support responses appear slow or lacking.
