Is LibriVox legitimate?

I've been hearing a lot about LibriVox, an online library that offers free audiobooks read by volunteers. But I'm a bit hesitant to dive in, as I'm not sure if it's a legitimate platform. Can you tell me more about LibriVox and whether it's SAFE and reliable to use? Are the audiobooks high-quality, and are there any legal concerns I should be aware of? I'd appreciate any insight you can provide to help me make an informed decision about whether or not to start using LibriVox.
