I am completely satisfied with this set to Speedminton-balls. Bought it as a complement to our squash rackets, as it is in fine weather a very good alternative to the rather expensive squash. With squash rackets can the balls also super play, contrary to some opinions that I had found on the net in this respect. We have tried the balls for the first time in the park and were pleasantly surprised about what distances you can play without the wind a one spanner in the making (with stronger gusts should already use the supplied wind ring). Very good, I like the strong shelter with screw cap that can get away anything. In five speeders for this price you can not go wrong! Clear recommendation!
