Review summary

User reviews describe Checker Plus for Gmail as a useful extension with strong notification features that help users stay updated on Gmail across the browser. However, privacy concerns and trust issues arise due to lack of open source status and potential data access, and there are complaints about account management and reliability, including a cap on free accounts and occasional failures when adding accounts.

Pros

Notifies you of Gmail activity across the browser, helping you stay updated across screens.

Cons

Privacy and data access concerns; not open source.
Account management limitations and reliability issues when adding accounts, including a paid upgrade after a small number of accounts.
