Walking Tour of Philadelphia

Our first time doing an audio tour and it was very disappointing. The information provided about each site was so shallow - some are basically mentioning the name and the date it was built/constructed and that was pretty much it. I could have easily learnt about it from Google. I was hoping there would be little stories like one would with an in-person guide. And the GPS didn’t work well - most of the time it didn’t pick up where I was. I had to manually search for the site. Over priced - I should have purchased another one half the price. The only good thing was the voices were clear and cheerful. Will not buy from this company again.
