There are reviews in the Android app, which is what I usually listen to.

Narration is a personal preference, but I've found many of the narrations are pretty good. Even compared to paid ones.

I work in a laboratory where I can go hours without the ability to even touch my phone to turn something on or off, or change volumes. So far, I've only been terminally annoyed to the point I turned it off, despite wearing acid contaminated gloves. For me, that's a pretty good track record.
