Word Wise highlighted 28 of the 2,800 unique words; turning it off eliminated the slight visual interruption for seasoned readers.

Setup Experience & Compatibility

Long-Term Durability & Reliability

After 30 days of daily reading, the file remained intact; no DRM‑related lockouts occurred. Customer support responded to a simulated “download stuck at 0%” ticket within 19 hours, providing a fresh link and confirming the issue was on the server side, not the file.
