Query: Intex Pillow Rest Queen Airbed with Built-in Electric Pump

I bought 6 of this airbeds on the 07 of Jun, 2009. My family used them and they have a lot of problem after each night sleep on them. They had to pump the airbed every times used. The air won't stay on last long in the bed. Now I couldn't return after we all shared the problem we had with each other. I feel so sorry to make a big mistake problem buying these airbed.
