A few days ago, I tried to pump up my bicycle tires. I had to borrow a pump.
The connectors and attachments suggested this pump would fill North-American and European tire tubes as well as air mattresses, soccer balls, and basketballs.
But the thing is, neither the pump’s owner nor I were able to make it work. We couldn’t pump up my bike tires.
Was it me? Was it the pump’s owner? Or was it the pump’s design?
If the user can’t use it, it’s broken (…or it may as well be).
