When will people stop digging for the lowest possible price? I would have paid three times this price to have a quality product. After three pumps the check valve that holds the air in the rocket failed. You would push the pump in and all the air would get sucked out of the rocket when you pulled the pump back out. Then the mounting nipple snapped off when releasing the rocket from the clamp. Never worked once! Would like to find one that works, but they all look the same.
A:
Negative
