The pump is very compact and fully functional. Especially that it is extremely quiet, I can only confirm. It feels too high and the processing is likely to be good. Super solution with 3-position switch (fountain on / off, or optionally with light). Unfortunately, the pressure is so weak that this pump was totally unsuitable for our indoor fountain, which is why I once again had to send back. I let myself from the statement of the previous speakers that it is very quiet induce to the weak model. The device is likely to be suitable only for mini fountains? However, the return was no problem at all. Professional handling with refund is selbstveständlich at this dealer !!
