Very good quality, as always with the Grohe brand. Bonde came with the mixer. Allow the putty to drain for not delivered. The rotation of 0 to 90 ° provides hot water economy, because most often a mixing valve is directed in front of the person and uses hot water often for nothing. No hot water needs for washing hands for example. I also think it looks more modern and it is no less practical than a mixer at -45 to + 45 ° angle. Satisfied with the purchase. 1 star less for the round trip to Leroy to putty.
