I have no problems like the previous reviewer. The gauge has a little arrow doodad indicator thing that you can set, just pump until you hit that mark then stop. I also have no problems with removing the presta only push on valve chuck. Just hold the tube valve with one hand and pull off the chuck with the other. I've never lost any air. The barrel length is long, it takes me about 25-30 strokes to inflate a 700x25 tire. All the Blackburn pumps I have ever owned eventfully go south and by the time they do (3-4 years) the parts are not available any longer. Other than that, it's a floor pump, gets air into your tires.
