Title: Works well for inflatable kayaks, after Boston valve modification
Review: We bought this air pump locally, and found it worked well pumping a large volume of air into the little press-in valves. However, when we went to pump up the hull of our inflatable kayaks we found that the pump's Boston valve adapter is too large in diameter for the values on our Sevylor kayak. Since the pump was otherwise good and inexpensive, decided to sand down the adapter a little bit. Works fine now.
