A few days ago, I tried to pump up my bicycle. I knew what to do: add air to inflate the inner-tubes. And I knew that I’d need a pump. I had to borrow one.
The connectors and attachments suggested this pump would fit two types of inner-tube valve as well as valves for air mattresses, footballs, and basketballs. So, an all-round useful pump.
But the thing is, neither the pump’s owner nor I were able to make it work. We couldn’t connect the pump to the valve. So i wondered, did the manufacturer test this product by putting it in the hands of first-time and occasional users, to see how it performed?
