User Reviews

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.

Pros

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.

Most issues here are user error not the fault of this app. Read all the docs people.

Got the basic version of the app to be able to read battery health info. Didn’t purchase premium version. I get 95% battery health reading without and 97% with extender attached. Does that mean that extender is super healthy and brings the overall health percentage up? It also shows 0 cycles in both cases. Not sure how to interpret that result.
