I was pleasantly surprised at the volume of the REX when it finally came on! It wasn't as long as I anticipated after watching videos like these. It was like a low hum at highway speeds. Not even audible with music playing. Of course, it seems more apparent at lower speeds but then it turns off when you come to a spot. I'm happy with it.
If you see my other posts, I have been having problems with lengthy charge times so I actually ran out of battery charge yesterday and was running strictly on the REX. Wow, am I glad I chose that option! lol :lol:
