Water Chariots - Anyone used their service?

Have you used the Water Chariots service which operates boat trips from Tottenham Hale and Limehouse Basin to and from the Olympic Stadium? If so I'd like to hear from you.

There was controversy about the company. Upbeat information by Water Chariots has met criticism because of the high level of fares. Which seems to have discouraged people from using the service. (In the final days of the games they cut fares drastically.)

I'm interested to hear the views of its customers. What was the trip and service like?
