Safety Gear

How does the “undefined” product on this page ( work with MP3? Does it have a built in player or SD slot?

Sorry about that, we changed the name back :slight_smile: I was also told “The MP3 function works via the Aux jack cord.”

Wow, Amazon really doesn’t like these.

One presumes these are battery powered but neither the “decripton” nor the “specs” makes mention of batteries, either size or number.
