Title: Does not fit Boston Valves, does not always work
Review: I bought this to inflate my Sevylor inflatable canoe, which has two pinch valves and two Boston valves. The Boston valve adaptor on this pump does not fit any other Boston valves, which rendered this almost useless for my needs. It works well for the pinch valves, but is a tremendously sweaty workout. Extremely difficult to use for deflating as well.
