Question: what size is it?
Document: This pump is lightweight and easy to use. Great price. Works perfectly for our inflatable kayak, inflating and deflating it.
The only way to go. Quickly inflates rafts, etc. Works much better than a single directional pump. If you have a raft or air bed or anything... get this pump!
The bi direction valve makes blowing up big things, like my inflatable kayak, a breeze! Durable and portable enough to bring down the river with me. Note:  I extend the life of these kind of pumps by putting a very tiny bit (a teaspoon max) of motor oil inside the barrel to reduce gasket wearing friction as the factory applied lube breaks down over a year with the heat of use.)
It's like the one we had before which was gray as pictured. The one we received is yellow and matters not.
Answer: no
