disappointed in the quality of the thread

A reception 2 ends of mounting tubes were plies.Avec pliers I was able to straighten them with the autres.Ensuite max out the rest of the installation no problem in particulier.Par against I play with my son who is 9 years old and hardly after a week of using the net is already déchirée.Je like a state that I am still in order, so it's keystrokes of my 9 year old son that tore at the filet.Sinon the size has nothing dire.Les tubes are not strong enough and the net is zero.
