Growsun Balloons Pump Kit Electric Balloon Air Pump Blower Inflator for Party with Extra Accessories

Do I need to turn the switch on and off each tome to fill a balloon or are the valves pressure sensitive?

How many feet of balloon tape do you get?

Does anyone know how/where the blue hose attaches & functions? Doesn't fit in any obvious ways. Seems common problem. Thanks.

Got wrong item what I do to get the right one
