I'd like to write something good about the pump. I have, however, bought her a bit longer, for my tank. The first pump has run for a few seconds. OK, I thought, have indeed guaranteed, but due to the design of my tank I had to cut off the plug to come with the cable outwards. So let's see if ne repaired or new or none get. A newly attached plug has nothing to do with quality or pump function and I know how to installed something, I've learned. But one could say: plug has been debt. So to Güde so. After a few weeks actually came a new one with an accompanying letter that the pump has been replaced as goodwill. Then, the second pump into operation. This time I thought I plug cut off until it pumps more than a minute. Cutting I no longer needed him: after a few seconds of pumping the pump life was again achieved. What ultimately there should be so difficult, I still do not know, another pump is doing but also what they should ... Maybe I have a Monday device, uh two get Guede devices ought but no longer in future be. From the beautiful blue Güde compressor, which I prefer I write nothing more. Sent back I no longer have the pump. Until the great pump is packed and my nerves are strained even further by any customer service cover letter ists effectively, the greed is good idea to bury the same.
