A lot of mixed reviews for this product unfortunately. Mine was perfect, but it is not realistic to blow this up by mouth. I had to use a machine pump and it still took 10 minutes. I would HIGHLY recommend buying some sort of handheld pump with an adapter to fit the air nozzle for this mattress. I'm sure they sell them here or on ebay, a bike shop too. Other than that I have no complaints. For hikers and backpackers, survivalists, buy an adapter and hand pump with an adapter. Buy some gorilla tape or patches to fix it up if there's a hole.
