I chose this model with not prominent buttons for design: cylindrical body, with no rough edges that the two water supplies (hot and cold) and the departure to the shower. The set is well finished with quality chrome. It works perfectly (almost instant temperature control). The knob on the valve is used to limit the opening (economy) but at my (flow and pressure in the low average) it is rather inconvenient: you have to constantly press it to achieve higher throughput standard Qualibre factory. While a change in the standard setting is possible according to the leaflet, with partial disassembly of the tap, but I did not started in this work.
