There are a few weaknesses to consider. Some users have pointed out that while the coverage checker is useful, compatibility features may vary across different makes and models. Additionally, while the tool offers a good range of functions, it may not cover every special reset feature available in some vehicles, limiting its effectiveness for advanced users seeking very specific repairs. Lastly, the need for AA batteries could be seen as an inconvenience compared to rechargeable options.
