The top-sheet of Adler is non sticky, very elastic and very durable. Actually the quality is the same as the top-sheet of Tiger only the sponge is a rather slow and soft one made in China. Adler is the perfect all-around rubber for all players who want to combine maximum control and spin but don't want to play a sticky rubber. Adler is a very good rubber for the weaker backhand side. It is also a good choice for all youth players, beginners etc. if higher quality then usual is wanted.
