Looks great next to the K7. Worked well for a few months but then started not popping back up. Pretty soon it stopped returning to the up position all together. Throughout this time we tried cleaning to see if there was dried up soap in the top and tried using thinner soap and watered down soap. Nothing seemed to help and we never could identify a cause. Ended up contacting Grohe for a replacement pump. Hopefully this one lasts longer. I'd still buy it again.
