Super material. This is the Grohe and it is perfectly consistent (and NF as well) Just to clarify, the angle of the control lever is slightly more than 90 degrees from the middle to the left which atypical but quite handy in the end (100% cold when the lever is in the center and 100% hot after lever is fully oriented to the left). Personally I installed it on a hand basin in the toilet and it's perfect. As against a bathroom sink that can be problematic. My advice, check through the diagrams in the product sheet to see if this product is right for you.
