During the Covid lockdown period, known as "Circuit Breaker" (aka CB) period in Singapore, one of my regulars advised he bought a tube to try with his kids.
The feedback is that it's more viable for playing in the outdoors and whatever you do - DO NOT USE YOUR BETTER racquets as the AirShuttle is build sturdier and thus heavier than your normal shuttle. Therefore there is much potential for racquet frame damage and for sure will put a smile on your regular stringer's face eg broken strings!
Thus do use your most un-wanted racquets when playing with these AirShuttles - the feedback received was fun for the kids outdoor.
