Basically, a good device to enhance the reflexes. Good alternative to the double end. High fun factor. But boxing beginners I would advise against the device sooner, because you can quickly acquire a false stroke technique hereby. For advanced users, a clear recommendation. Would start with the green ball - which is difficult in the beginning enough. A star deduction is available for the high price. However've found no effective alternative ... The self-construction manuals on the Internet (tennis ball with elastic waistband ....) is what Frickler who feel like and time, do not think that this rankommen the playability of Reballdo. Just enter for usage instructions Reballdo at Youtube.
Update: Did the Reballdo for a year now and the rubber is unexpectedly not torn. Order me the (smaller) orange Reballdo because me this has now become too slow.
