I tested for you for several years. In 2014 she just let go after 6 years of loyal service. When purchasing She looks nothing (actually it is quite "cheap" at first) but it works very well. This shower for use is quite loud and the jet is very powerful (you can cheerfully clean soap scum on the walls and floor of the shower without rubbing) so pay attention to skin that fear pickling. But you get used to that power quickly and neck massage with her is too great! And if in addition it saves water why not use it! ? By cons as it replaces some of the water with air, the air cools a little water and I feel it uses a little more hot water than another shower at the same temperature but less water at all ... so I support and love!
