From this point of view, nothing to say nice finish, without any concern mounting, the drive seems very strong and probably last long.
As it has filters, including a reduction of water consumption, and that a larger head diameter than the average, it has the disadvantage of its advantages: If you have a water flow "normal" do not expect a forceful shower, even with the "massage" function. Indeed it takes a powerful enough speed to be able to get a toned stream of water through the showerhead.
For me that's enough. For my wife it is less satisfactory. Matter of habit ...
