I can pump up my raft with that $10 walmart cannister 2-way job in about 20 minutes. It just takes a lot of huffing and puffing. But if you switch off with someone else it is not nearly as bad. I imagine if I used that pump exclusively for inflating my raft it would not have lasted this long though. Who knows? I would be curious to hear other stories on longevity of the cheap cannister pumps.
