My Klargester was serviced by an engineer named Tim who was professional, courteous and demonstrated good personal skills.
From the outset he asked whether I knew or wanted an explanation of how the Klargester works. I did and he gave an explanation that I understood. He carried out the service and gave useful advice on servicing, what to do if there is a power cut and the parts and spares engineers carry with them if required.
I was most impressed with the service he gave. He is a credit to Binder.
