Quiet as a mouse

I absolutely love how quiet this is. There's nothing worse than a loud aquarium when you are trying to relax and enjoy your fish. This is so easy to install basically right from the box and then you just clip it to the side place the hose where you want it. Its a very long hose so you should have no issue with placement and then just plug it in and you are good to go. It works just like it should and isnt very big so you barely notice it on ours because we put it on the side facing the wall. It works great for our 5 gallon and now our 10 gallon after we upgraded. I'm happy with it.
