Replacement Dog Exerciser Rings for 100-ft. Flying Ring Launcher | Replacement Rings Only (Launcher Not Included) | Set of 6

where is it made?

Where is this made/manufactured?

Instructions said line the ring up, turn the band counter-clockwise, pull back as far as possible, launches 10-15 feet at best....what's wrong here?

Where do I buy replacement rubber tubing/bands? I have two that are both worthless without them.
