The only pumps I own in my house currently are Mini Mac Light Pumps (I cannot compare it to others in short). The pumps during ideal weather perfectly inflates most 260Qs completely with one smooth pump (slow or unsteady motions allow air to escape). There are very few 260Qs I have tried pumping up that the pump does not like (silver is one - stiff balloon and leaves a short tail).
If you are having trouble with the tip complicating blowing up larger balloons (i.e. 360/660), use a tip I learned somewhere on this forum of taking some balloon scraps and placing it over the lower section of the nozzle. I have done this to the point that it nearly makes a perfect seal with a 646 balloon. The top half of the nozzle is bare for use with 160s and 260s. This idea has not complicated my efforts of blowing up the smaller balloons with this pump.
I would offer more comments if I had them, but the basic story is this is my first floor pump and I am glad to have something that does a great job.
