In relation to the price, the pump is first class. For a ball 65 cm by 200 strokes are needed and who says that one makes with the ball gym ?. Since it is very smooth so you can easy to pump until shortly before "Armabfall", but then the ball is at attention very nice. Have to think about the compatibility with the ball valve also worry. Always fits! A little tip on the edge; Always full stroke exploit ca. 12 cm otherwise you need to "Armabfall" yet 2 hands to carry on. Buy recommendation!
