It's heavy !!, Lots of solid metal. Beak very long and high, rare in valve catalogs. Quality Chrome. Well designed, large ceramic cartridge, normally guarantee of reliability. Flow limiter 50% in handy. Fixing the serious sink with 2 screws instead of one ordinary nut. Mixer asked to replace the model "Best" from the same manufacturer, to look very similar, but with a body in two parts instead of one for Ceramix Blue. "Best" is sold only in GSB, barely cheaper, as the name suggests, it is deemed to flee in qqs weeks or months. With me it was the next morning !! Remains to be seen over time.
