no negative comment

Perfect for my 240 liters aquarium

First thing I have noticed about this wave maker, it is so lightweight. But I was optimistic, because I have other products by Hygger, and non of those disappointed so far.Second thing was, although it has suction cups on both sides and a magnet, the inside part with actual wave maker can be moved so easily, regardless the magnet on the other side of the glass. So easily that one of my fishes bumped on it and it moved entire wave maker (the fish is not that big, trust me).So, I have installed this 1050 GPH wavemaker in my 55 gallon tank, and the output power is disappointingly weak, Bearley has any effect.Friend of mine has a 550 GPH SICCE wave maker in same 55 gallon tank and it is way more powerful than this 1050GPH. That SICCE cost 100aed more, but you get what you paid for.And one more thing happened, after maybe 5 hours into "making waves", impeller started making like clicking noise, like it's hitting something while spinning, so I opened it and removed impeller and put it back in place and it stopped making sounds.And yeah, wave maker is not loud, but it's not silent either..So, overall bad and disappointing experience.Sorry for long review guys, hope this long post will be helpful for Hygger as well, to improve future models.Cheers

Literally stopped working after a few days or user, forgot to put for return now the window is closed...sad...really sad
