@hh1 people who are good at technical things are wonderful people, but, as I discovered long ago with the guitar, sometimes it can create an impression that only an expert can do something.
But if pumps were intended only for experts, they would be of very limited value. Obviously once someone works out how to use it, it gets easier, but you shouldn't be intimidated, even if the learning curve has a bit of a slope on it, it doesn't mean it's not worth taking a climb up it.
You'll probably amaze yourself at what you can do.
