Pure fun to .........

.... Yes until the 2nd holiday at the surface formed an approximately 40 x 30 cm wide and 10 cm high bump. Since the upper layer has probably disconnected from the main body (delaminated). And although the board was exposed to direct solar radiation. Even in the cold ocean water or at low outdoor temperatures at night the bump did not go away. We had our daughter on vacation to buy a new (un-cool) board, and of course the local prices were twice to 3 times as high as here in Amazon.
After returning from vacation comped us the seller the full purchase price. Great praise and thanks to Sport-Otto!

For the board therefore only 2 stars, for the merchant but full 5 stars!
