My sister bought ds this football target game from ELC. It looks cool, but when dh tried to inflate it, he found he couldn't get the cross bar to stay up, because the inflating nozzle doesn't have one of those one-way valves in it, so the air started to escape before he could get the plug in. Has anyone managed to make it work properly? Or do we need to return it? (And if we do, can anyone suggest something similar that works properly?)
