Query: Never once failed me over the years

I've owned several of these over the years and never had a major issue with one. A little bit of force always gets the plastic needle seated in the bleeder until its time to pull it out and switch wheels. Remember to empty the bottle into a bigger bottle when you move to the next wheel and you shouldn't have an issue with leaks or spills. I've never had a problem finding a place for the magnet to stick but have heard of people using part of a clothes hanger to hang it in place while pumping the brakes.
