User Review: i have an Intex Seahawk II. with this pump I can inflate the main chambers and floor twice as fast as with the standard supplied pump. as for deflating, the floor and seats have squeeze valves and the supplied adapter fits to deflate them, however I don't see any way to use the pump to deflate the main chambers, not that it is realy needed, when the Boston valves are fully opened air releases quickly. it would though be nice to draw the air out of the main chambers to get them flatter, it would be easier to fold up and put in the carry bag. there may be a way to deflate via the Boston valves, if there is I havnt figured it out yet. when using the pump hose as if to inflate, and changing sides on the bottom of the pump itself a great deal of pressure is needed and it doesnt feel right, the faster inlfation in my opinion makes the pump well worth the price.

iv used this pump three times now inflating my Intex Seahawk II. I can inflate each if the two main chambers in about a minute, the floor under a minute, the two seats a matter of seconds for both as well as deflating the seats. still don't know if main chambers can be deflated with this pump, or at least I havnt figured it out yet, I hope so, that would be great. this pump is the way to go, its very light wieght and works great.
