Very interesting to have a soundtrack with a very knowledgeable guide. Just don't go to fast our you will be ahead of the commentary.

Enjoyed the narrator and the app worked great. So glad we did this !

It was awful. First you could not find the beginning of the tour. Second there is no reception at all in the mountains for it to play. Total rip off. Tried to get my money back and it said I was past the window.

This is not worth it ,is a scam I could Google this

Super

It was not good. Would not open at all. Could not use it. Do not order this was a waste of money.

Worked like a charm and the history along with advanced warning of pull offs was huge.

Very informative, but sometimes the story was cut short

Good idea but not practical. Too much traffic and roads closed Couldn’t use it. Waste of money.

Easy to use and great information especially for a first time visitor wanting a general tour of the area!
