Customer Review

had me last year, two pumps for the cat fountain (Lucky-Kitty who cares) ordered after the provided had given up the ghost.
The pumps are actually too strong for Bunnen. This has been described another buyer.
I like it - now I have a well and no trickle.

Sometimes vibrate / grumble the pump quite well. But goes away again when nachhilft with Knock-knock!

After more than a year are now both broken. Is probably the calcareous water. I clean the pump while regularly in citric acid, but after 4-5 cleaning baths it was then.
I wish that you can open the case better to clean them. That's just brutal to accomplish, and what ever breaks.

Nevertheless, I'll order the pumps me again because I find nothing comparable.

If anyone has a good idea for cleaning, go ahead!
