Sprint Reader - Speed Reading Extension

Sprint Reader is praised for significantly saving time, improving reading speed, and its high customization for speed reading. Users find it very helpful for productivity, focus, and proofreading, and value that it's free with features often behind paywalls elsewhere. Common issues include occasional skipping of words or punctuation errors, lack of voice reading, shortcut key problems, difficulties handling non-English texts, and an annoying frequent update popup. Overall, users appreciate the extension but desire enhancements like better language support, more settings, and a less intrusive update notification.
