This air pump is hard to tame. I have not hung on the wall (it has a suspension device) but I think my neighbors are happy and grateful about it, otherwise the whole house would vibrate. Although the little monsters pumped powerful air into the tank, but is not to keep on a level surface. The vibration it travels from A to B, making a huge racket. It was only when I use the air pump on a soft towel (folded several times) have laid, it was absolutely calm and so very very quiet: D
The Sprudelstein is anything but robust, it broke apart while trying to dismantle it again and join a figure to the hose. But when ordering we were doing anyway more at the pump.
The hose is so long that you have enough left over to lay a few more Luftsystheme.
