content: Brand new and though it pushes air and the gauge seemed to work, I couldn't get a proper connection with the valve to inflate two different bike tire tubes. These same tires inflated fine with another pump made by a different maker.After reading other reviews of this and other bell models, I get the impression that these pumps are hit or miss. If you get a good one, it works fine. You may be better off spending $30 to get a more durable pump from a different maker with better quality control.
