## Review summary

The recurring complaints about STUNLOCKER focus on licensing and the derestriction feature failing to deliver, poor support, and feature restrictions that limit compatibility. Other issues include unclear licensing availability and non-working region/units settings. A few users note some basic functionality exists in the free version, but the overall sentiment is negative.

### Cons

- Premium license often fails to unlock derestriction or the option does not appear, making the main advertised feature unusable.
- Customer support is unresponsive or unhelpful, leaving users with unresolved issues.
- Claims of broad compatibility with Shimano motors are misleading; derestriction is limited to specific models/firmware.
- Premium licensing/availability is unclear or inconsistent (questions about whether the license is still available).
- Region and unit changes (e.g., USA region change, imperial units) do not work as expected.
