New input: Dear potential sucker,My first airbed by intex sprung a leak in about a week, so I obtained a refund. I bought this model next, and it lasted almost twice as long!I am now on my third. I should have learned my lesson, but my current intex airbed has been around for about one year, and currently has 9, count 'em, NINE leaks. Everytime I patch one, another springs.Intex also makes inflateable boats. They must get sued for a lot of drownings. No wonder they have no email contact. If you buy ANY intex airbed, you are buying utter garbage.Sincerely,SidWa State
