what r your opinion on trampolines?

hi dear i got a trampoline for my son but he fell off it and got a bad sprain ..it actually scared me so much that i have packed it off now..i i have got a air jumper for him which has risen sides so that he does not fall off and it is not as bouncy as a trampoline..

There fun, great exercise..I actually learned how to flip very well starting on the trampoling and slowly moveing to the ground..It's a great workout, and if your worryed about injuries theres nets you can buy and put around it to stop someone from flying off..I like to show off though and do front flips and back flips off the trampoline
