waste of money - (Ab) Switching function too sluggish

if you like I will irrigate einzellne pots, the system is not suitable. How to design such a stiff usability is a mystery to me. I have set to a shift but that is so hard to use I did not expect. I have to irrigate every few days my conservatory I expect an easier handling and therefore I'm looking for a andres system chosen with pressure lever that you also can not undress by telescoping rod.

DANGER
The return shipping for the Gardena lance has over 23 cost me - (! Breakage) because the seller has shipped without proper packaging cartons and the part was wrapped in delivery only in bubble wrap I had an extra charge for special packaging to pay what is usury of the post though but also indirectly blame the seller, the division of packaging
