However, the part began some time ago more water from the mixer lever to press as came out of the tap itself.
Original manufacturers contacted, the shock got at the exorbitant price (incl. Shipping about 54) and a look to Amazon thrown.
Was initially surprised to the low price, but I ordered because I had no desire to replace the valve.
The replacement of the cartridge went well out of hand, the fit was given and since then only come as water out where it should.
In Conclusion: Fast shipping, good fit, easy replacement and currently we are highly satisfied with the tightness.
My wife is happy and I had less work ;-)
