I like the different attachments and they are firmly tied to the unit so they are not floating about.
I have a similar pump with the Sevelor brand (I've seen other names on them too) that I bought about 7? years ago and have been very happy with it. I added about 15' of 12/2 wire so I could fill the entire boat on the trailer with the pump connected at the back of the car and a short piece of hose that fits all my valves. It still puts out over 1.8 PSI (I just checked it) and has taken lots of abuse, I don't think you could go wrong for $45.00.
