Query: Low price and low quality

I'm a inflated bed fan since I was a student in the past three years with frequently moving. Three month ago, I bought this for my mother-in-law when she's coming visit us.Now it is just broken after only 3 month usage. One seal breaks (I did not do any funcy thing on it). As a compare, my two and half years old aerobed is still working good without any leaking.Pumping gas into this bed is much more difficult than into my aerobed.BTW, it's too soft, macro-soft.Price is low, which earns one more star for it.
