Query: boat is fine; pump and oars are not

The pump is so flimsy that the rubbery-plastic parts lost their seal and let all the air escape on the very first use. I sealed them back together with super-glue, but given the cheap construction I'm sure that it will come apart again next time.Worse yet, the oars are quite useless outside a backyard swimming pool. After every stroke they must be re-tightened to stay together (the cheap, plastic pieces of tubing screw into each other) and within 30 minutes they had cracked.The boat itself, however, is quite nice and works just fine for two adults or three children.
