the playground close to my house is a tough one as, due to a presence of dust, ground, leaves and small broken brunches coming the concrete surface is never perfectly clean and, as small as they can be the remains after a the rough clean we can give the add up to the hardness of the surface. We always called it the ball killer. Tough test for the street phantom but I was pleased to see that it passed the test brilliantly: the hard rubber of the ball has coped perfectly with it and I am pretty positive I am going to enjoying playing there for long. 5 stars deserved. Congratulations
