I like foam soap - hence the Keuko foam soap dispenser is an asset to my bathroom. To the more disappointed I was when after about 3 years, pump the soap dispenser was so stiff that they often got stuck - and then, alas no longer (as described in the instructions) had made functional. The out ordered loose spare pump (without chrome / outlet) was a big disappointment - could not connect properly with chrome structure and hooked behind not much less than before. But now I wanted to Schaumseifenspender why not scrap - actually liked him so - and the holes in the tiles were so bored. But to operate the donor just neat. Therefore, some time later a second attempt - with this pump "chrome" - ie the actual pump chrome plated structure.. Changing course is super easy - just (like the soap refill) old pump out, and then instead the new pump pure - and works perfectly again as the first day. For full marks.
But beware: the price of the pump are highly variable - and partly simply outrageous (about 40 euros). I bought the pump here at Amazon for 28 € - and find the necessary price still OK. At times, you will find the pump price comparison portals for 16 Euro (and if you then still ordered a stock Schaumseife there free shipping) - this is then a good price-performance ratio. (For the price no penalty - you have to wait, if necessary, maintenance and / or where order otherwise - because the price is in this case, rather than a cause of the seller Product feature).
