Although the one-touch operation simplifies usage, it may not cater to all users' preferences for more advanced settings. Some users may also find the lack of real-time monitoring (like live listening) a limitation if they desire immediate feedback during recordings. While the lifetime warranty adds peace of mind, the reliance on a single battery raises concerns about longevity in very long-term use.
