Manila - very satisfied, a much better option than the thieving taxi drivers with their battered old bangers.

Bangkok - Used once to the airport at B500 flat rate which is more than a taxi would cost IF the meter was used, however try finding one who'll turn it on.

London - Cheaper than a black cab and just as good. From an airport hotel to Terminal 4 the cost for two passengers was the same as the Hoppa bus.
