User Reviews

ThinkDiag+ is a capable, affordable diagnostic tool with a broad feature set and solid support, highly valued by DIY users for value and usability. However, recurring subscription costs, mixed UX, coverage gaps for certain vehicles, and iOS/app stability concerns are recurring drawbacks to weigh against the benefits.

Pros

Very versatile, feature-rich tool capable of controlling, testing, and diagnosing many vehicle systems.
Strong value for money; affordable bidirectional scanner compared to expensive alternatives.
Easy to use and helpful for preliminary diagnostics.
Good app-to-hardware integration, appealing to DIY users.
Reliable customer service and support.

Cons

Ongoing subscription costs after initial period; perceived as expensive.
UX/UI can be obtuse and not always intuitive; needs improvements.
Gaps in vehicle/brand coverage and some models lack certain diagnostics; some firmware/update issues.
iOS app reliability and cross-platform compatibility issues; some functions/workflows don’t work as expected on iOS.
Reports of accounts or activation issues and concerns about devices being dependent on subscriptions.

Recent reviews

The version of this product I purchased is supposed to allow me to read error codes, and even to reset them, yet even properly connect to my car. Documentation is worse than poor. Customer support is even worse. The only useful thing I can do is to monitor real time data from the engine, but that’s not what I need.
