I am 16 years old and I would like to learn to play tennis at least a little. Rockets are quite expensive, do you think that only a child will be enough for me? I looked at her in the store and she was big enough.
Try to look at the Bazoš.cz advertisement, you may also find a cheaper racket than in the store :) I recommend the Junior Rocket. otherwise about the size of the racket, consult an experienced tennis player, not a trader who will sell what he wants, because he wants to sell!
